Plymouth boot splash screen with nouveau.modesetting=1
Are you able to boot with "nouveau.modeset=1 drm.debug=1" and attach the resulting /var/log/messages to this bug?
Will do tomorrow - thanks for the quick reply!
I'm seeing the same thing on a GeForce 8600M GT (rev a1) on a Macbook Pro. I'll attach three photos (of poor quality, unfortunately) showing what I'm seeing.
In short, I don't see the plymouth boot, and the colors are all wrong once X comes up.
I too will try with "nouveau.modeset=1 drm.debug=1" and attach the

The kernel complains that this is an unkown boot option, but apparently sees it OK anyway.

Bad colors with nouveau.modeset=1, zoomed in

Here's my /var/log/messages file. I gzipped it since the original was huge (just over 12 MB)!
Thanks guys. I'd be curious to know how things are now with kernel-2.6.29-21.fc11? There's some changes in there that may possibly help.
F11 snapshot live cd works OK my 8600M GT Macbook Pro, the test day Live CD did not - please test.

Sweet, I'd say this issue is likely resolved then. Though, I'll wait to hear from the reporter before closing. Thanks!
I'll try to test this on Wednesday and let you know how it goes.
The kernel/xorg drivers in F11 snapshot 1 LiveCD work great with nouveau.modeset=1 set on the kernel command-line.
A big hats off to all who helped get this fixed!
Yup, works here to with the UEFI test day live image. Thanks for the quick fix!
