Some (probably silly) suggestions...
o Try underclocking (!) the CPUs. Maybe 400 or even 350MHz?
o You say that both SMP and UP kernels hang. If you swap the CPUs around,
do they both still hang? (ie. is the _first_ CPU faulty!)
o You have quite a lot of kit packed into the box. Perhaps the power
supply is misbehaving. ATX power supplies aren't expensive. Get hold
of a new 300-400W PSU and give it a whirl
o Is there adequate ventilation in the box? If you were to point a
desk fan at the machine's innards, would the machine run more
reliably?
o The old `append="mem=511MB" instead of 512MB' chestnut. ;-)
