I tried this tree (specifically, a merge of Linus' fb20871 this tree) on 
Fedora 11 with modesetting enabled on an integrated Radeon 2100, and 
plymouthd crashes immediately with a corrupt page table.  Photo 
attached.  After the crash, bootup stops, although ctrl-alt-del works.

This is on a Gigabyte GA-MA74GM-S2 (RS690 chipset) with a somewhat old 
BIOS which has never had reliable graphics on X with any kernel and 
userspace I've tried, modesetting or otherwise, so this isn't a 
regression per se.  But on F11's kernel, I can at least boot to a 
console with modesetting enabled and nothing dies until I try to start 
X, and, with modesetting off on older kernels I can boot just fine 
(again, until I try to use X, at which point things break).

I'd be happy to test things to help debug.

Thanks,
Andy
