I'm sort of confused. I'm currently running 2.6.11. Are you asking me to 
go back to 2.6.7 and try it?
May 18 00:38:49 xen Linux version 2.6.11-xen0 (root@xen) (gcc version 
3.3.5-20050130 (Gentoo Linux 3.3.5.20050130-r1, ssp-3.3.5.20050130-1, 
pie-8.7.7.1)) #1 Fri Apr 29 11:15:24 EDT 2005

I believe I can still boot the original Gentoo (non-xen) kernel. I will 
try and reproduce it there.
