That won't be a Linux kernel, though. Sorry, but with 128k of RAM
there is no chance...

You will be able to run PPCBoot on the box, which support I/O to the
keyboard and the LCD on the MPC823 (although this is stil work in
progress); you will even have elementary network support (BOOTP /
RARP / TFTP).
But you cannot run the normal PPC Linux kernel in 128 kB RAM.

Start porting PPCBoot (see http://ppcboot.sourceforge.com/), then
continue adding RAM :-)

If programming was easy, they wouldn't need something as complicated
as a human being to do it, now would they?
