Hey Peter,

I've got it running on my board now after figuring out how to wire up
external interrupts in EDK.  :-)

Good success with keyboards and mice.  Events come through no problem.

Some block devices seem to be giving me grief.  I have no problem with
my SanDisk ImageMate CF reader.  However, I've got a SanDisk Curzer
Micro that gets reset during transfers.  Is this something you've seen
before?  Log output is below.

I've also got a QuickCam Messinger that I'm going to test isochronos
transfers with as well.

Cheers,
g.
