[PATCH] vesafb: Disable mtrr as the default
vesafb occassionally gets the size wrong when setting the mtrr. When X or DRI attempts to set the mtrr, it will fail due to range overlap significantly affecting their performance. Disable mtrr and let the user explicitly enable it with the mtrr:n option.
