I was able uname to output for uname -mpi:
alpha alphaev56 alpha

uname -m show information returned by uname glibc call (which in turns
calls kernel. I remember tracing that a long time ago).
The -p and -i is handled by "uname" and have some altering code for
other arches. I'll install modified version of uname and see how other
programs would like the new output. :)

Rgeards,
