this might hapen for your Cirrus Logic video board,
but there are many cards I know of where just restarting
the X server usually works fine (and reboot etc. too).
many users would be happy to know just _that_...

at least for S3 cards and some others this isn't true (even if they
use overload registers etc. too).

if you know so much about Cirrus chips (I don't) and suffer(ed) that
problem yourself, did you ever think about improving the exit handler
of the Xserver for Cirrus? or is it impossible to solve your problems
there too (why?) ?
