Hmm.  There's something wrong here.  It should report "PCF8583, 32.768 kHz
clock".  I've been getting the same problem (and occasionally "event mode,
stopped" on my A3020 -- I'll slap a logic probe on the I^2C bus and see
what it's playing at.

To do that, you'll need to arrange the that the router provide a root path
for the R140.  If you can get it to emit arbitrary DHCP options, this
should be possible.  If not, you'll need to run dhcpd on your SPARC (or
use RARP/bootparams).

There's nothing arm26-specific you need to do if you're loading the kernel
from disc.  You'll need a DHCP server and an NFS server, appropriately

This isn't surprising -- I don't have a driver for it yet, and since it's
in a fixed place, the kernel doesn't trip over it like it does over
surprising podules.

I've added that to sys/arch/arm32/podulebus/podules.  Note that the arm26
podulebus code just prints the podule's on-board description (if it can
find it) rather than having the entire podule list compiled in.

Hmm.  From the messages it looks like it's starting up in an odd state,
since the AKA-30 can't take a 16-bit ROM and the podule ID looks like
