Suspend/result works fine with the 2.6.31-10-rt kernel, so this seems to be some sort of kernel regression. I also have other random crashing issues on the 2.6.32 kernel that appears so far to not occur on the 2.6.31 kernel, I'm not sure whether that's due to a seperate issue or not. The crashes are very like that mentioned here: https://bugs.launchpad.net/ubuntu/+source/xorg-server/+bug/585765
The bug can be reproduced (on this laptop at least) by simply suspending the machine and then trying to resume it. The resume fails with a black screen and no apparent way of gaining any further response from the system.

This should be fixed upstream in kernel 2.6.35-rc4. From the changelog:
commit 580b4fffbbdc3c8
Author: Dave Airlie
Date: Wed Jun 30 13:26:11 2010 +1000
drm/radeon: add quirk to make HP nx6125 laptop resume.
For some reason on resume, executing the BIOS scripts locks up the whole chipset, by avoiding the dynclk table the machine resumes properly and seems to function okay.
