You are right single cpu machines - but for SMP machines the linux
kernel is broken
in such a way the usualy newer version is always better then the
previous version
(with some minor exceptions) - also some of some likes ReiserFS, Ext3,
AGP, DRI, EMU...

I guess most of the people are interested in i386 platform so you
wouldn't
have to fight with ppc for now (at least from my point of view :))

I may send you my patches - for both 2.4.12 - or 2.4.10-ac10 - in both
cases
RTL seems to work - examples also work (though I've also slightly
modified
basic rtl distro)

But the problem is - as you mention - softirqs - I would appreciate the
help
in this area (otherwice I would have to go too deep into the kernel
sources)
