There are free variants around as well - XtratuM/PPC (RTLinux-4.0) is
running on 440EP/GR and 405 Octobus, im quite sur RTAI also is available
for AMCC CPUs - check RTAI.org (mailing list link is to be found there) 
and rtlinux-gpl.org (mailing list link) - those lists are most likely the
best source for the free-software hard-realtime Linux variants.

Not really. RTAI is a dead horse for anything except x86.

Instead, look at Xenomai ==> www.xenomai.org
