Well, I actually thought about this enough once to give you this advice:

1. Only consider the 18F8x20 series, which can use external program memory.

2. Don't consider using the CCS C compiler.  It has many bugs, foremost
not accepting valid C for structure declarations and function
prototypes.  You'll be rewriting uClinux until the cows come home.  Try
microchip's C18.

BTW, why don't you port some form of linux to the AT91RM9200-QI-002-ND
(digikey part#)?  If you can get it to boot to a shell and single-step
with GDB, I'll pay you $250 for your design on may 1, and $500 if you
get some more things I need working.  I need this for an upcoming
project and can't afford the $5K for the dev kit.  Does it count as a
microcontroller?  Its a 32-bit ARM9.  There is already an ARM linux
distro.  I could be convinced to make a simple "eval board" if you are
serious about getting linux to run on it.
