OHCI problems on HP MicroServer

[Stephen Borrill <netbsd%precedence.co.uk@localhost>]

Got a new HP MicroServer which is a nice little device.
It hangs when booting netbsd-5 or -current which I've tracked down to an 
ohci problem. Disabling ohci gets it working (I tried boot -12).

I enabled ohci_debug and the last two lines were:
ohci_rhsc: sc=0xcb7d8000 xfer=0xc1ed6400 hstatus=0x00000000
ohci_rhsc: change=0x00

I've attached the dmesg and the hang is just after the ahcisata lines are 
displayed.
