I've played many AVI files without MTRR support.  It will still work, just a 
bit slower.  If programs won't run at all (as in the case of MMX and 3DNow!) 
then we should compile different kernels.  If they just don't run as fast 
then we can let the users compile their own kernels.

If you want maximum video speed you want to compile your own kernel with AGP 
and DRI support etc...
