Oh well, I don't think that my work collides with anyones else work. Just
hacking the GNU libc and the necessary kernel interface changes. BTW -
switching from H.J. Lu's libc to the FSF's release I'll have to modify
GCC 2.7.1-1 a little bit. This affects only the ELF flavoured compiler and
for people that don't feel like recompiling this could also be done by
hacking the specs file.

For separating out the high/lowlevel stuff in the console: as already
mentioned often enough this has already been done for the Linux/68k and AFAIK
this work is being reused for Linux/Sparc. We should do the same. I however
don't consider doing this hack my part of the job - the board I'm using is
mostly VGA compatible and makes only minor modifications necessary.

Hmm... Suggestion for hacking Milo's libstand.a. How about converting
\n into \r\n in sprintf()? I always feel pretty nervragged when I once
again forget the \r and the screen output get garbled.
