Well, I'm now only working on some documentation, so I think I can run some
tests if they are automated enough, on either i686 or x86-64 machine (both
SMP). There's about 5 - 10 GB of free disk space on each (ext3, but I can
create a reiserfs easily, if needed).

If you want me to do this, please provide me with:
a) patches to test,
b) benchmark tools,
c) instructions (what to turn on/off in the kernel config, how to run the
benchmarks - I need to be able to use a text editor while they are running
and occasionally run a web browser or acroread, but I don't care much if the
system crashes on them).

Yours,
rjw
