Does SRM configure all PCI devices?

Maybe I'm barking up the wrong tree, but I'm trying to get a PCI USB 2.0 
card to work in my AlphaPC 164, but am getting this:

uhci0 at pci0 dev 9 function 0: VIA Technologies VT83C572 USB Controller 
(rev. 0x61)
uhci0: interrupting at eb164 irq 3
usb0 at uhci0: USB revision 1.0
uhci1 at pci0 dev 9 function 1: VIA Technologies VT83C572 USB Controller 
(rev. 0x61)
uhci1: interrupting at eb164 irq 0
uhci1: controller did not reset
uhci1: cannot start
uhci1: init failed, error=13
ehci0 at pci0 dev 9 function 2: VIA Technologies VT8237 EHCI USB 
Controller (rev. 0x63)
ehci0: interrupting at eb164 irq 0
ehci0: dropped intr workaround enabled
ehci0: EHCI version ff.ff
ehci0: wrong number of companions (15 != 1)
ehci0: ohci or uhci probably not configured
ehci0: companion controller, 15 ports each: uhci0
ehci0: reset timeout
ehci0: init failed, error=13

configured function 0 of the PCI devices? The USB card is the only PCI device installed that has more than
one function.

On other alphas, SRM has restrictions on what slots can have multifunction cards.  This might be true for
your system.

options PCI_NETBSD_CONFIGURE 

might help.

Ah, I'll try moving the card around then...

Hmm, it looks like that's not currently supported on alpha :(

pciconf.o: In function `pci_do_device_query':
/usr/src/sys/dev/pci/pciconf.c:491: undefined reference to `pci_conf_interrupt'
/usr/src/sys/dev/pci/pciconf.c:491: undefined reference to `pci_conf_interrupt'
*** [netbsd] Error code 1

There aren't any mentions of PCI_NETBSD_CONFIGURE in sys/arch/alpha.
