I ran into this same problem with a SMC card and a P90.  I fixed it by
rebuilding a kernel with the RAM address for the card set to d8000 rather than
c8000.  I think this can also be fixed by rebuilding a kernel with the fd* line
changed as follows:

before:
fd*     at fdc? drive ?

after:
fd0	at fdc? drive 0
or
fd0	at fdc? drive 0
fd1	at fdc? drive 1

If you look at the mailing list archives on ftp.netbsd.org or one of its
mirrors you should be able to find out the relevant messages.

Hope this helps,
