Sure, go ahead and try the second patch that adds the Netmos cards to the
serial driver's device tables. It is for a somewhat newer rev, but you might
just get offsets with no failed hunks. It's worth a try.

The serial driver will only detect cards that are in the table. It does not
mean that there is anything wrong with the card.

Good luck,
Ed

I just found this:
http://www.uwsg.iu.edu/hypermail/linux/kernel/0212.2/0845.html

Has this patch been accepted into the new kernel series? Or should I 
just toss this card (the NetMos PCI I/O card)?
