For some reason the SuperIO puts the RTC at 0x400, even though it's
usually at 0x70. If I put it at 0x70 the keyboard and mouse don't
work :( I put it at 0x90 and corrected the size so that it wouldn't
conflict with other devices. That makes Linux happy with it. It
still could be a problem for Windows not to have it at 0x70.

Sorry I must have misunderstood this again. I thought this was why I
keep getting : IRQ9 nobody cared messages from Linux.
It's the last thing that Linux complains about. I'm not sure what I
should do so that somebody cares.

It's mostly working.

Yes. I was trying to implement what I thought was the intent of the
original. Since then I've taken out the VGA IO port regions and the
DRAM region. It's a lot more complicated because I have multiple root
buses. As far as I can tell the factory BIOS is also not 100%
compliant with the spec, which is making it harder to see what's wrong
My current state is hopefully better than what it was when I first
submitted these patches, but the BSOD is the same.
