I'll send you some code. Most of it is design specific, but there are
parts that deal with MMS windows which are more or less design
independed. Note you'll be covering Flash with MMS window.

Having RAMDISK on onboard Flash is not best way to do things - Flash
will break after 100K (?) writes. Flash is good to store kernel image
and initial read only root partition, people who use ROM's can adopt
this idea without big problems.
For 'bulk storage' you can use ATA solid state/or mechanical HD
in PCMCIA slot.

Yes, I wrote Flash chip drivers myself and from what I see it's
more or less exactly how Linux accesses PCMCIA plain flash cards,
I was able to build Linux file system on PCMCIA flash card.
