I just ported (almost copy&paste) the code straight from your driver. The hard part was fiddling around with the various segments, groups etc that are used to force the data at 70:xx. Eric remarked that before restoring interrupt vectors the code should probably do a CLI which your code does not do either. I'm suddenly worried about the IRQ vectors too, as they are redirected if STACKS>0. Might look into that later...
