The PCI device 6 function 0 at PCI bus 0 has both I/O and memory mappings
disabled. For sure, in such a situation, a driver is unable to drive the
device. It is the job of the PCI BIOS to assign these resources to PCI
devices prior to booting the O/S.
The PCI BIOS of this machine is bogus or the SCSI card is broken.

'cat /proc/pci' output should be interesting.

Right. INT A for single function PCI device is what the PCI spec says.

I would be very surprised if this one on this machine does. :)
