I compared with i810, and the functions are identical (see for yourself):
http://gitweb.freedesktop.org/?p=xorg/driver/xf86-video-amd.git;a=blob;h=30047ea0d3058f0ea9cb147ba1168edf7b87bd21;hb=d4cd5d91a015088d548736831edd31760bcda88d;f=src/amd_gx_driver.c#l1484

and 

http://gitweb.freedesktop.org/?p=xorg/driver/xf86-video-intel.git;a=blob;h=a6c13ed724536a43f9f9a7c9dba92250443e4da4;hb=5cbb4110116f6d4187fd27660a78203caa1da46b;f=src/i810_driver.c#l852

So at this point, its clear we're walking into a trap somewhere in the 
VBE code and not coming back.  At this point, I'm afraid the course of
action is to slog forward and figure out what part of the VBE code is
breaking.  Then we might get a better idea of what
our options are.  I would help, but unfortunately, I don't have any hardware
handy that breaks (unless the db61 would suffice?).

If you need anything, e-mail, or find me on IRC.
