Strange, according to ahc driver's source code (I don't have spec.),
AIC7870 should be probed as PCI device, not EISA device.
Does someone know why ?
# There is new ahc driver which is port of current FreeBSD's code
# (by Pete Bentley), but it doesn't seem to cope with this case.
# It treats aic7870 as only PCI device.

Another hack you can do is
1. add following statement to sys/dev/isa/aha284x.c:ahe_probe()
if (sig_id == 0x78 && sig_id == 0x70)
ahc->type = AHC_AIC7870;
2. add "ahe" driver for your config file as
ahe0 at isa? port 0xfc00 irq ?
scsibus* at ahe?
(port 0xfc00 means slot 15 of eisa device)
3. config && make && reboot
