Make sure you have the firmware in your initrd if you are using modules, or
built into the kernel if you built radeon into the kernel rather than as a
module. See the "Troubleshooting Extra Firmware" section of this page:

Comparing the initrd of 2.6.37 and 2.6.32 show they are both the same, and
neither of them have any firmware in them. They didn't actually have the radeon
module at all.
I compared /lib/firmware to the git repository
http://git.kernel.org/?p=linux/kernel/git/dwmw2/linux-firmware.git , everything
matched (I checked with md5sum) except the newer
BARTS/CAICOS/BTC/PALM/SUMO/TURKS firmware which I assume is all later than my
card.
I tried to force update-initramfs to include the radeon kernel modules by
listing it in /etc/initramfs-tools/modules, but this caused the
update-initramfs to hang when loading radeon.ko in.
Rather than try to insert everything manually in my initrd, I blacklisted
radeon in /etc/modeprobe.d and modprobe'd it in after a complete boot to a
virtual terminal.
On my old kernel, this worked swimmingly (no radeon in lsmod, module loaded
nicely). On the debian stock kernel modprobe hangs, I stopped timing after ten
minutes, the screen doesn't resize as usual for KMS, lsmod lists
radeon/drm/drm_kms_helper. dmesg again shows only RS780 Microcode being loaded.

:/ Sorry, my last paragraph was a little ambigous.
On my old debian 2.6.32 kernel, this worked swimmingly (module loaded nearly
instantly, screen resolution jumped up).
On the debian 2.6.37 kernel modprobe hangs, I stopped timing after ten minutes,
the screen doesn't resize as usual for KMS but lsmod lists
radeon/drm/drm_kms_helper. dmesg again shows only RS780 Microcode being loaded.
In each case, before starting, I checked with lsmod to make sure radeon was not
loaded.
Since my last comment, I also checked Ubuntu 10.10 (2.6.35), and it has
graphics issues as well - it is much harder to see what is happening because
plymouth gives me a blank screen, but it also has a modprobe timeout,
apparently no KMS loading, and firmware seems to be available in /lib/firmware.

(In reply to comment #4)
> [ 4.414321] radeon 0000:01:05.0: WB enabled
Does passing the parameter no_wb=1 to the radeon kernel module help?
Alternatively, does disabling the integrated RS780 GPU work around the problem?

It doesn't seem to help. `dmesg | grep WB` shows it as Disabled, but modprobe
still hangs on load at the RS780 firmware.

Works. With the RS780 GPU disabled, everything functions.
BIOS -> Advanced Chipset Features -> Surround View -> [Disabled], KMS works, no
modprobe hang.
I didn't know that that card could be switched on and off. Thanks :)

Owen, can you bisect?
Just trying a few intermediate versions from http://snapshot.debian.org/ would
already be useful. For narrowing down the regression range beyond that, "git
bisect" can help:
git clone git://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git
cd linux
git bisect start -- drivers/gpu/drm/radeon
git checkout (bad version)
make localmodconfig; # minimal configuration
make -j2 deb-pkg
dpkg -i ../(package).deb
reboot
# confirm that it is actually bad
git bisect bad
git checkout (good version)
make silentoldconfig; # reuse configuration
make -j2 deb-pkg
dpkg -i ../(package).deb
reboot
# confirm that it is good
git bisect good
# now it checks out an intermediate version to test
make silentoldconfig
make -j2 deb-pkg
dpkg -i ../(package).deb
reboot
git bisect bad; # if it hangs in the same way
git bisect good; # if it boots correctly
git bisect skip; # if some other problem makes it hard to test
... rinse and repeat ...
git bisect visualize; # to watch the regression range narrowing
git bisect log; # to summarize partial results if you get bored
