OHCI, like UHCI, is also USB 1.1, just a different standard. EHCI is USB
2.0.

I have a VIA chipset USB 2.0/FireWire card in my Ultra 5:
...
ehci0 at pci2 dev 3 function 2: VIA Technologies VT8237 EHCI USB Controller (rev. 0x63)
ehci0: interrupting at ivec 1a
ehci0: EHCI version 1.0
ehci0: companion controllers, 2 ports each: uhci0 uhci1
usb2 at ehci0: USB revision 2.0
...

It also supports UHCI for USB 1.1 transfers. I haven't tried the card yet,
but the kernel finds it at least. Concerningly, I see this as well: 
ehci0: unrecoverable error, controller halted
ehci0: blocking intrs 0x10

The other card in the machine is a Symbios 875, which is seen fine, but
doesn't have any disks attached at the moment (although it has worked fine
in the past in this machine).

Hmm... I've had similar failure to power up problems, but only on PeeCees
with buggy ACPI implementations. I assume your PCI riser is properly seated
etc? What IDE card do you have installed?
