Argh! Little bit of googling helps around "no idea"s...
For every one else facing my problem:
dd if=/dev/mem of=~/mem bs=1k count=1k
xxd mem > dump
The dd part has to be as root, the xxd (or every other hexdump program) part
should be as unprivileged user.

acpi_scan_rsdp() finds of course the signature at 009c4b0, which is in fact no
RSDP block, the RSDP block is at 00fdfb0. The working 1.02 BIOS is filled up
with zeroes around 009c4b0, this is why the older BIOS is working. If you
need more dump, just mail me.
Thank you very much ;)
