Well. At least the patch applied and the kernel came up:

[oliver@gosa ~]$ uname -a
Linux gosa.beer.linux-kernel.at 2.6.29-0.28.rc4.git6.1axp.fc10.alpha #1 
Sat Feb 14 08:07:29 CET 2009 alpha alpha alpha GNU/Linux

It's headless, so quite hard to say if drm locking is fixed or not, at 
the moment. But it's informative for Jay, that he can try this kernel 
:-) If he has time...
