I use the chromiumos tree (for chromiumos 2.6.38 kernel:
http://git.chromium.org/chromiumos/third_party/kernel-next.git) with some
additions to make it run on the AC100. This modified tree is on
git://gitorious.org/~marvin24/ac100/marvin24s-kernel.git. The config is
paz00_defconfig and a dmesg you can get e.g. from http://pastebin.com/9uVfDWma
(it's not very current, but it should be sufficient).
I'll add Stephen Warren from NVIDIA to the CC list. He has more HW to test on.
Btw, this is the patch I used: http://gitorious.org/~marvin24/ac100/marvin24s-
kernel/commit/cce8d9e25d009a45c219a6ad0b9ac4e27d034ab0
