there would have to be some more stuff to add to get it working on
non pc hardware. like setting up the virtual interrupt vector table.

we currently just get a copy of the first megabyte of physical memory
thru '#v/vgabios' or '#P/realmodemem' wich contains the real ivt of
the host pc that was prepared by the system bios on bootup.

ron probably knows how todo this :-)

the kw openrd in fact does have a vesa-capable pci device, but it's not clear
to me that the vesa bios exists on the part as shipped with the openrd.
