Hmm.. from my last look into the aha174x driver. The driver simply does
only detect a single card. In theory you can make it detect and support
all cards. I think a similar thing was done for the aha154x driver already.
The aha174x will have to keep track of each adapter and dispatch command
between them. So quite some changes will be required. I dunno if you want to
do that though it should be bearable and worth the efforts (if you really
need two aha174x) IMHO. However your mileage may vary.
The aha174x driver lurks in linux/drivers/scsi/aha1740.c (as if you
didn't knew that) where most (if not all) of your changes will go.
P.S. Please take care not to screw the driver. I like that my system
simply works from the first day I ran it. ;-)
