I have build a snapshot sys.tbz2 from the current-cvs tree. All packages
are compiled for i486-pc-linux-gnu and this
version definately runs on K6 machines.
I modified the autoinstaller.sh script to suit to our changes. If you
configure your system the manual way, what is preferd, you must change
i686 to i486 in /etc/ld.so.conf.
I think the package is available on ibiblio in about 3 or 4 hours.
