Of course, this would be just after one of these random crashes.

I have considered lshw very reliable so far. Have you started it with the admin rights?
(sudo lshw).

What does "cat /proc/cpuinfo" return ?

lshw shows a core duo and a pentium III.
…

→ Could you check in the BIOS to see if there is an additional PIII CPU showing
and enabled? (And if so if it could be disabled)

It does not show agpgart-intel and after a fast search in Lubuntu vbox, in my own
Archlinux box and on the web it seems not to be provided anywhere anymore.

I don't quite see how zram would interfere with the GPU abilities. Are you
considering trying the values I have pointed to in the last mail here ? "Date: Sun, 22
