I new version (again). Here the change for this version :
   - No more modification of the hvm_info_table.
   - Creatation of a SCRATCH zone for hvmloader : 0x1000.
   - Copy directly the VGABIOS at the right place (0xC0000) into the 
guest memory.
   - Detect which graphic card are present in pci_setup().
   - Remove the function cirrus_check
   - Add the support for some special keys for the dom0 driver.

---

This patch is for pass-through the principal graphic card to a hvm guest.

This is what is done inside :
   - We map the VGA frame buffer into the guest's memory (0xa0000 -> 
0xbffff)
   - We get the vga bios address into the guest memory. Etherboot has 
been moved to 0xD0000 to let enough space to load the dom0 vgabios (it 
could be pretty big).
   - Map the vga ioport 0x03c0 -> 0x03df.
   - Then we start qemu with the new option -dom0-driver to have the 
dom0's keyboard and the mouse redirected into the guest.
