Hopefully, some people can give you more details on handling the flash
and other requirements....
One thing you might want to look at until you can get the flash stuff
operable is the linux router project :
http://www.psychosis.com/linux-router/
It allows you to make a machine with a 1.44Mbyte drive act as a router
(Its a way of running a minimal linux).
Also :
http://luz.cs.nmt.edu/~rtlinux/
Which allows linux to run "hard" real time tasks (linux exists as
a subtask to the real time system).
Some of the howto's describe how to run Linux from a serial
console....
(Has this been changed in later kernels ? ).
good luck,
wes
