Comment 36 for bug 943263

@Thomas - Thanks for your feedback - the upstream kernel developers did add the following comment to this patch:

"radeon: initial fix for VGA on LLano system, 3 or 4 of us have spent time debugging this, and Jerome finally figured out the magic bit the BIOS/fglrx set that we didn't. This at least should get things working, there may be future reliability fixes."

I've checked the kernel DRM-next tree but there is nothing there yet. Let's wait and see what is included in the drm pull request for kernel 3.5.

Can you confirm that disabling DPMS (power management for the display) keeps the display visible?
