Go ahead. I assume you can now open the attachments? If you could just
make one small modification; all controllers but Oktagon use a 40 MHz
clock. The zorro_esp driver versions I've been spamming to this list all
have carried a bad 20 MHz clock setting for the Blizzard 2060 board.

I've actually been able to compile the driver into the kernel and use it
for root fs (on my Blizzard 1230-IV).
