Morning,

No change here either. I'm running current as of about 30 minutes ago
with your patch + "zyd* at uhub?". Everything works great, except for
the cardbus slot which mocks me with
pccom4 at pcmcia0 function 0: can't allocate i/o space
When I insert a pcmcia card (some random Xircom 100MBit + 56k modem).
