This is on our own board.  We're developing a optical wireless transceiver
system (see www.omnilux.net) and we use the Au1000 as the central
controller.

It's a pretty simple board -- the au1000 static bus interfaces connects to
FLASH, and two external peripheral devices; one of them being a PCMCIA card.
(We put the card directly on the bus -- no "end user proofing" buffers or
any such things).

The non-PCMCIA peripheral sits within the directly accessible low memory
range.  In fact, outside of user pages, the only thing that needs TLB is the
small windows pointing to the PCMCIA card.

If you can, which board is this on?
