I did, but to no avail. Their problem description also differs from mine: I 
get pretty good performance with video or normal DGA access. It's when I use 
the special xmame effects that I run into problems with. Now as said: it 
works perfectly well with the Morphix CD I've used, but using the X 
configuration from that setup doesn't help either.

I've tried editing the /proc/mtrr, but it won't allow me to do so (writing is 
not allowed, but writing rights of file and directory are set). I was hoping 
perhaps the answer could be found by using the Morphix mtrr settings. If that 
doesn't help, then I should really consider having a good look at my kernel, 
and try a vanilla kernel or something. Perhaps SuSE played around with the 
mtrr support in the kernel...
