But as far as I remember, the 8086 could address more than 64kBytes of Ram,
although the Rest of the Processor was 16-Bit...
On an Platform where the Address-Bus is also limited to 16 Bits, meaning
only 64KBytes of Ram (without using _really_ dirty Tricks as the Apple ][
did). This seems to be too little memory for uClinux - even _if_ you somehow
get the kernel into those 64KBytes, there will we no space left for
userspace apps, a rom-fs image,....).
Maybe you would be better of if you just take the things you would need from
uClinux (like maybe the TCP-Stack, .....) and put the together in one
