RFC: Disk-On-Chip filesystem.

>From looking at the data stored in the 4Mb device I've got here, it doesn't
look like M-Systems' latest 'TrueFFS' is in fact a form of FTL.
So I'm a little lost as to what to do with the device. Offhand, I can identify
1. Reformat the device with FTL.
Pros: It works immediately (well, as soon as I work out how to physically
write to the device, anyway).
Cons: FTL is patented in some legally-backward parts of the world.
The built-in BIOS code stops working -> we have to write our own
bootloader that runs from the flash.
2. Try to decipher the format that's actually used.
Pros: Data will be interchangeable between DOS and Linux on the devices.
Standard bootloaders will work, via the BIOS.
Cons: It may prove difficult and slow to reverse-engineer the filesystem.
It may turn out to be a FAT-specific hack, rather than the general
block-device that FTL provides.
