@David Benjamin - Regarding the second paragraph of comment #76 - this
may be related to the errors reported in comment #75. This has been
fixed upstream in kernel 2.6.37. From the changelog:
commit a93f344d3c04e4b84490c65f2a574387c593be40

drm/radeon/kms: reorder display resume to avoid problems
On resume, we were attemping to unblank the displays before the
timing and plls had be reprogrammed which led to atom timeouts
waiting for things that are not yet programmed. Re-program
the mode first, then reset the dpms state.
This fixes the infamous atombios timeouts on resume.

Ubuntu 11.04 "Natty Narwhal" is using the 2.6.38 kernel.
This patch was also included upstream in kernels 2.6.36.3 and 2.6.35.11.
Confusingly, it's mentioned again in the upstream changelog for
2.6.35.12, so I'm not sure whether that means it wasn't applied properly
in 2.6.35.11. Either way, the 2.6.35-27.47 maverick kernel is based on
2.6.35.11 and the 2.6.35-29.51 kernel in maverick-proposed is based on
2.6.35.12.
