This will answer all questions but leaves FireWire out, unfortunately- there
is it theroretically possible to run a Linux system on this Handheld PC
(it's a MIPS VR4122 processor [180 Mhz] in a JVC MP-C33 Handheld PC).
At the moment I just want to find information about this, because I think
that it will not be possible to simply flash the system and the device is
not very old.
4. HPFS driver?
