mtrr: type mismatch for d0000000, 8000000 old: write-back new: write-combining`

[Andy Graybeal]

Should I be worried that this is appearing in my dmesg?

mtrr: type mismatch for d0000000,8000000 old: write-back new: 
write-combining

it looks like this has to do with ATI.  I don't really use the 
computer's VGA connection, it runs headless.

I don't know if this just started happening or if it's always happened 
and I never noticed it.
