[PATCH] vesafb: Set write combining for framebuffer memory
Edward,
the problem is that the vesafb driver attaches itself to the AST device and
disables write-combining by default. Current the only solution is to boot with
video=vesafb:mtrr:3. In this case, vesafb will do the right thing and enable
write combining.
The attached patch makes vesafb clean up the memory config after unloading. But
it won't help as we currently never unload the driver.
