It did not work out too well with mem=nopentium.
The boot process did hang 3 times due to
a problem specific to my BM: MS-6570 K7N2 Delta
For some unknown reason the "Athlon Powersaving mode"
has been enabled by the BIOS or simply by turning
on the power. This facility is simply unstable
with MS-6570. The CPU stops completely, and I have
to turn the power off and on.

My solution is to call the athcool program in rc.local:
athcool off

athcool version 0.3.0
 enabling/disabling Athlon Powersaving mode
 
nVIDIA nForce2 (10de 01e0) found
disabling 'Halt Disconnect and Stop Grant Disconnect' bit ...  done
 Address 0x6F : 0x1F -> 0x0F

This solves the problem. It should really be
done at the very beginning of the boot sequence,
but I don't know how to do that.

It looks as if the "mem=nopentium" somehow
is increasing the instability.
