.32.

and then I backported the DRM/TTM/KMS from 2.6.34 to be able to test the
nouveau driver.

Yes. I think so (isn't that the default thing?). Played some tuxracer
when testing it on Radeon and I think the i915, so the OpenGL components
worked OK. I know that 3D don't work on the nouveau driver so hadn't
tried that.

Yes. I used for initial testing with whatever was in F13 Alpha drop?. After
all of that testing I switched my main desktop machine to use F13
with the using xorg-x11-server 1.8.0-12.fc13 and with a GeForce 8600 GT.

It works - thought I keep on getting those PSE warnings whenever an application
has been killed (http://wiki.xensource.com/xenwiki/XenPVOPSDRM, look for
Status).

HA! Working on that and S5 right now. Jeremy mentioned he did get S3
working, but hadn't tried other modes. S5, S3, and S1 on my SuperMicro
XF8TN just don't work. Not sure if I have the Xen ACPI hypercalls
thought in the code base.
