One note about this. If you're using LPC2400, I think that's an ARM7.
TDMI so no MMU which I think matches your mention of uclinux.
Unfortunately, defio has a dependency on MMU. There are other
possibilities to achieve the same effect but I'm not familiar with the
2400 and I'm not sure if it can do it.

Oops, sorry, didn't notice that part. Yes, it depends on the presence of
a MMU.
