This looks good.  I want to get PCMCIA working then the CF card will
work.  If you're feeling brave, you can try to help me debug it. :-)  I
don't have a logic analyzer, but I think something is wrong with the
addressing i'm using.  Unforunately, at least with DDB's "mach tlb"
command, I'm not seeing the problem.

The other bits that would be useful to know are how the PCI interrupts
are routed along with IDSEL information (this could impact whether or
not PCI works at all!), and  any board specific CPLD registers.  (Used
for reset/poweroff/identification.)

Thanks!
