I have. I run a dual G4(7400), also with CONFIG_HIMEM and got plenty of
random SIGILL's, SIGABRT's and deamons crashing upon startup until I
started using Ben's bk tree.  I've been using 2.4.20-ben(x) for quite
some time now without this problem.

Try rsyncing ben's bk tree and using it, it cleared up this issue for me.

rsync -avz --delete rsync.penguinppc.org::linux-2.4-benh
