To make a looong story short, I swapped out the hard disk, the
controller, the cables and all memory before concluding that a heavy CPU
load reliably produced corruption and/or a system freeze and finding out
this was caused by faulty cooling on the first CPU. I have an Asus
P2B-DS, and I can provide more detail about this horror story if anyone
wishes. Why isn't there more space between the two processor slots on
this otherwise good board ?

Already did that once in a past accident on the same machine, but for at
the time unknown reasons. That time, pppd was still running and a little
"for" loop running on the package list that apt gave me did the trick.
Today, I guess I'll have to burn a few CDs...
