This looks like a dupe of bug 16140.

Created an attachment (id=26921)
--> (https://bugzilla.kernel.org/attachment.cgi?id=26921)
dmesg after suspend/resume test with radeon.agpmode=-1
I don't see those error messages from bug 16140
In any case, I tested with radeon.agpmode=-1 and my problem is still there: the
computer freezes on resume with a black screen.
Also, boot parameter radeon.agpmode=-1 with echo core > /sys/power/pm_test
behaves as before: system resumes from suspend but I get a black screen. The
computer is still alive so I can capture a dmesg and reboot.
I attach the dmesg.

dmesg after suspend/resume test (2.6.35-rc4)
There has been some improvement with 2.6.35-rc4
With the rc4 the suspend/resume test works fine:
$ echo core > /sys/power/pm_test
$ echo mem > /sys/power/state
The laptop suspends for a few seconds and comes back fine. The display works
and everything seems ok. I attach the dmesg I captured after this test.
However, the actual suspend/resume still doesn't work. The symptoms are the
same as with rc3: the laptop locks up on resume.

dmesg after suspend/resume test (debug test)
I was able to get more info about this bug.
I added an early return in the radeon resume routine with this patch applied on
top of f469461df6ff822f71b8737bda86eea20f16ff93
--- a/drivers/gpu/drm/radeon/radeon_device.c

I booted this kernel and did a suspend/resume cycle, saved the dmesg and
rebooted. After the resume the display was black but I was able to save the
dmesg and start the reboot. The laptop locked up on reboot.
There are some new interesting error messages in the dmesg:
[drm:radeon_ring_write] *ERROR* radeon: writting more dword to ring than
expected !
[drm:r100_ring_test] *ERROR* radeon: ring test failed
(sracth(0x15E4)=0xFFFFFFFF)
[drm:r100_cp_init] *ERROR* radeon: cp isn't working (-22).
radeon 0000:01:00.0: failled initializing CP (-22).
I attach the full dmesg just in case.

Created an attachment (id=37792)
--> (https://bugzilla.kernel.org/attachment.cgi?id=37792)
dmesg after suspend/resume (2.6.37-rc2+)
Current git kernel 2.6.37-rc2 (actually at
b86db4744230c94e480de56f1b7f31117edbf193) still has this issue.
I got another dmesg after a suspend/resume cycle by using the same patch as in
comment #5. There doesn't seem to be anything new but I'll attach it here just
in case.
These are the steps I take:
- boot patched kernel (console only, no X)
- run this:
echo mem > /sys/power/state ; dmesg > dmesg.log ; sync ; sync ; reboot
The laptop survives the suspend/resume (with a black screen) and writes the
dmesg to file but hangs on reboot.

The driver has changed so much that this bug report is really obsolete. If you
see the problem with a modern (3.2/4/5 kernel) feel free to update it
