Maybe this will shed some light on the situation. Also, with my  
hacked up bge driver, when I try to up the interface, uhci1 host  
controller halted shows up if it didn't break on boot already.

...
uhci0: host controller halted
...
uhci_freex_ xfer=0xc2e55200 not busy, 0x0000009e
ehci0: handing over low speed device on port 4 to uhci1
ehci1: handing over low speed device on port 4 to uhci3
uhub2: port 4, device disappeared after reset
uhub6: port 4, device disappeared after reset
uhci1: host controller halted
...
uhci_freex: !isdone
uhub1: device problem, disabling port 2
uhci_freex: xfer=0xc2f2b800 not busy, 0x0000009e
...
cd0(piixide0:1:0): using PIO mode 4, Ultra-DMA mode 2 (Ultra/33)  
(using DMA) <-- this is a SATA DVD-ROM/CDRW, I can't imagine it's  
getting away with UDMA2.
