I have a Promise card with a 53C810AE that is not recognized.  So I don't
   know if it is a Promise thing, or just the fact that it is a "AE" part with
   a different PCI id.


i have a `tekram dc-310' which has the same 810ae on it... it works OK in
NetBSD, but the pc164 SRM doesn't like it...

siop0 at pci0 dev 6 function 0: Symbios Logic 53c810a (fast scsi)
siop0: interrupting at eb164 irq 0
scsibus0 at siop0: 8 targets, 8 luns per target

[ yes, the driver reports the wrong thing. ]
