Thanks to Hiren doing the Picostation work, this Buffalo is now running!

I'm going through the GPIO pins today, if I don't get any other
outstanding issues.

Item1:  UBoot is not giving me a functional rootfs partition.  I
emulated the OpenWRT behavior to get it working.

Item2:  there are 2 16M Flash devices.  Linux seems to concatenate them
into one device.  I'm looking at spi(4) to see if it has that type of
capabilities.

Item3:  Unable to cfg_save. I don't think I have the cfg part mapped
correctly:

dd: /dev/map/cfg: Input/output error
0+1 records in
0+0 records out
0 bytes transferred in 0.250469 secs (0 bytes/sec)
