That's real. /sys/dev/buslogic/bt.c:bt_port_probe() contains:
...
if (bt->model[0] == '5') {
/* DMA settings only make sense for ISA cards */
...
} else {
/* VL/EISA/PCI DMA */
info->drq = -1;
}
so I assume the probe message is correct and reasonable.

The only comment I can find is in bt_isa.c:bt_isa_attach() - which
refers to a hardware bug in older h/w revisions (I'm fairly certain I
have a RevD card - which is affected). F/W 3.37 only runs on RevE
cards and is being used to guess the hardware revision. This bug only
affects cards where the BIOS is enabled - and I don't have the BIOS
enabled so it shouldn't affect me.

I tend to agree, but I'm not sure how the card is expected to behave
in this situation. The manual only discusses booting off SCSI disks
attached to the card - which I don't have. There's no indication of
what would happen if the BIOS is enabled when there aren't any
bootable disks. I was hoping someone else might still have a system
with a BT-445 and be able to confirm the normal behaviour.
