Hmm, might have misspoke. No framebuffer is used on my boxes running gentoo. Not sure were I pulled up that atyfb interferes with xorg drivers but atyfb was known to cause problems for some (maybe unrelated to xorg).
However, there is a gentoo bug for this same mmap error with xorg-server 1.2.0: http://bugs.gentoo.org/show_bug.cgi?id=167052. My gentoo boxes are running xorg-server 1.1.1 and my ubuntu box is running 1.2.0.
In any event, adding "video=atyfb:off" caused the system to lock at "Booting Linux..." right after loading the initrd. The md5 of the current /usr/bin/Xorg binary is different from either of the two listed on the web page so I'm not replacing it with the debian one mentioned.
