Can't speak to Debian, so I may be at the limit to what I can recommend based 
on what Fedora does. Sorry my xorg.conf didn't help.

Understand, fbdev is an Xorg module, not a kernel module. The output 
of 'lsmod | grep fb' on both my F8 dom0 and my F9 domu is (null) - ie: no 
modules loaded with 'fb' in them. Also, F8's dom0 is based on 2.6.21, further 
underscoring the kernel version has nothing to do with this. It might very 
well be a newer Xorg is required. My F9 domu fbdev comes from 
xorg-x11-drv-fbdev-0.3.1-7.fc9.i386.rpm. Back when this domu was F8, it was 
xorg-x11-drv-fbdev-0.3.1-4.fc8. This is generally Xorg 7.2/7.3 with 
xorg-x11-server-Xorg 1.3 (F8) or 1.4 (F9). I believe I remember you saying 
your domu was CentOS, which probably means an older Xorg. I've never 
installed a CentOS domu.

Sorry, but I'm probably not going to be much help now :-(
