when i had set it to 32M i get the funky smearing effect if i ran 
glxgears.  16M is refused to start X, less i got those funky errors 
above.  *shrug*

i have a /proc/mtrr if that's what you mean:
reg00: base=0x00000000 (   0MB), size= 512MB: write-back, count=1
reg01: base=0x1ff00000 ( 511MB), size=   1MB: uncachable, count=1
reg02: base=0xf8000000 (3968MB), size=  64MB: write-combining, count=1

am i supposed to do something with it?
