This finally works fine with the attached patch from Xavier Bachelot.
I've also attached the xorg.log when using it.  The screen also looks
way better then when using the proriatery driver, thanks!  :-)

If you'd like me to do some more tests I probably won't be able to do
too much as this is really my parent's computer and I live in a
different country normally.  Since I'm leaving them again today and
have no remote access due to a silly ISP, testing further things will
be very difficult and slow.  But I can try if you would like me to.

Merry Christmas
