Serial Interrupts are definitly not working. I'm now running the uart in 
polling mode and I had to force use 16550A mode. Below is a patchset of my
hacks.  You need a fixed posix_types.h and bitops.h, too. I haven't tested 
the cvs version, yet.

Thomas.

PS: I'll be next week at Systems in Munich. You can find me at the Linuxpark 
HP booth (hall A3, No. 404-22) during the whole week.

   This device has completely bogus header. Compaq scores again :-|
It's a host bridge, but it should be called ghost bridge instead ;^)
