Hi,

OpenBSD simply scans the PCI-bus for devices in order. You see this in
the lines:

> pciide0 at pci0 dev 8 function 0 "CMD Technology PCI0680" rev 0x02
> fxp0 at pci0 dev 10 function 0 "Intel 82557" rev 0x08: irq 5, address
> fxp1 at pci0 dev 11 function 0 "Intel 82557" rev 0x08: irq 10, address
> pciide1 at pci0 dev 17 function 1 "VIA VT82C571 IDE" rev 0x06: ATA133,

so your motherboard controller comes after the pcicard, that's all. With
proper root device and /etc/fstab everything should be working. I would
not try to compile a kernel because it is only necessary to change
/etc/fstab, boot with option -a, select the new root device and use
config to store the changed configuration into a new kernel-image.

Regards

Stefan Kell
