If vesafb attaches to the AST device, it configures the framebuffer memory for uncached access by default. When ast.ko later tries to attach itself to the device, it wants to use write-combining on the framebuffer memory, but vesefb's existing configuration for uncached access takes precedence. This results in reduced performance. Removing the framebuffer's configuration before loding the AST driver fixes the problem. Other DRM drivers already contain equivalent code.
