You are using vesa framebuffer ? We likely not save and restore
all register properly. Does the crash reboot the computer ? If so
try remounting the /var partition with sync option before doing
this so you can get a full xorg log. Oh and if it reboots the computer
it might be that for some reason the framebuffer mapping is
reseted to its initial value and we did not set it back (copy and
paste code at top if avivo_screen_init function into the leave vt
function after restoring the other states.

Do some radeondump -d oscr before closing the screen (remember
to do things like changing resolution, moving mouse, launching apps
btw each dumps) and do radeondump -d cscr after closing & reopening
screen (same do things btw dump but do not change resolution
just move mouse, launch, resize apps). dcomp csrc oscr which
should give a list of interesting register to look at, you can send
me dumps or output of dcomp.
