-current, uhci.

Here's dmesg from the machine.  uhub0 and uhub1 are the two sets of two
ports built into the machine.  Other devices only sometimes work.

The machine also semi-frequently fails to boot, stopping during the twirly
cursor phase.  I am starting to suspect that there may be a memory sizing
or allocation problem; the linux image I had reported a few extra "unusable"
areas via ACPI.  If a given kernel fails to boot, and I power-cycle, it may
or may not boot the next time.  The linux and Windows images never had this
problem, so I'm guessing they are luckily stepping around the problem.
