I had a look at the source and I think implementing
host bus mode is fairly easy, however I don't know how :(
Is there some sort of API documentation for X drivers?
(e.g. is there a non-pci equivalent for xf86MapPciMem(),
 how are multiple Device sections handled wrt the driver
 entry point, ...)

All header files have the argument names conveniently omitted..

Thanks,
