We don't want vga16fb to mess with hardware initialized by other driver. Detect it and refuse to load. It fixes nouveau interrupt storm on some machines.

This is an update to the Linux part of the Xen PVFB. Linux Xen PVFB is a pair of Xen para-virtual frontend device drivers: drivers/video/xen-fbfront.c provides a framebuffer, and drivers/input/xen-kbdfront provides keyboard and mouse. Their backends run in dom0 user space. Parts in this patch series: 1. Enable Xen console by default in domU 2. Pointer z-axis (mouse wheel) support 3. Module
