It is a single-processor Intel Pentium III (Coppermine) at 700MHz.
The chipset is an Intel one, lspci calls it "Intel Corporation 440BX/ZX/DX - 
82443BX/ZX/DX". The Computer was an old system from Siemens

1. Up to know I don't have the required cable, but I first added fb-console 
with higher resolution, to also get beginning of panic-message.

2. I'm going to install the kmsgdump patch from

to trigger the crash.
