There is a patch thar works:
http://www.atnf.csiro.au/~rgooch/kernel-patches.html
(the MTRR-Patch, the later versions patch against kernel > 2.1.9x, I
think). This Patch solves the BogoMips problems which I also had on my
IWill-Board and also adds MTRR-Registers. It is included by Linus in the
latest Kernels.

I used 2.0.33 quite a long time on a ordinary Pentium system
(WWW-Server, Samba (heavy load!), FTP...) and had no problems all the
time. I would
say that it really is more stable than a NT System - good choice.

Currently I use the 2.1.101(2)-kernel on a IWill DPentium Board (with
heavy load) and it seems to be really stable. But, of corse, you are on
the saver side to use 2.0.33. Check out wwww.linuxhq.com for security
paches.

To improve performance I can also recommend to use the pgcc-compiler to
compile apache, libc and other often-used stuff. It really increases
performane a lot!
