Yes, it's a dual 450 MHz PII and appears to have no
problems. Certainly, there are no surprises when I run two
pipes at once -- they take about 11 seconds of real time,
roughly twice the real time of one pipe with the "rsh
trick".

This is under 2.2.5. Do you need me to run this under
2.3.29? The problem is that I can't get my ethernet card to
work under 2.3.X -- there are complaints about System.map
when I boot and I am clueless about how to fix them.
