This bug has additional info on the freedesktop buzilla:

https://bugs.freedesktop.org/show_bug.cgi?id=21480

The core problem seems to be that when running in KMS X is unable to
allocate any memory and from that point everything else is doomed to
fail.

Comment 3 Alex Bennee 2009-05-25 08:38:26 UTC 
Tested on RC7 and I can now boot X and get some sort of display. I have other problems with KMS but I think this bug can be cleared now.
