I'm not fan of the config space option .. I don't like vendor specific stuff in PCI config space. I prefer adding a DISPI VBE register since we never compile that out (despite the ifdef's being still around) do we ? I've tried to engage with the Bochs folks on their mailing list to make sure they agree in principle at least but have had no reply yet. Cheers, Ben.
