eisa0 at mongoose0 ?

Hi,
I'm interested in getting an EISA ep(4) card to put in my 735/125.
http://www.openbsd.org/hppa.html shows mongoose(4) as unsupported,
however my dmesg is deceiving me to believe this page may be out of
date.

mongoose0 at mainbus0 offset c000000 irq 17: HWPC000 rev 34, 33 MHz
eisa0 at mongoose0
isa at mongoose0 not configured

Could I reasonably expect an EISA ep(4) to work on such a machine?

On a related note, I have an ISA ep(4) at the moment. Are ISA and EISA
compatible? Can I expect to one day see isa0 at mongoose0 ?

Thanks,
Graham
