This should work out of the box (with changes to the toolstack) to work
under x86 right? I would have to do some 'vga=none' to disable the VGA
framebuffer?

With this you can disable emulated vga:

About xenfb FWIK you need also another patch already posted to support xenfb on hvm domUs:

I already tested vga=none but not xenfb on hvm for now.
