just to let you and google know: it worked out. i upgraded the bios to
version 3.03 (took me 10 floppy disks to find a working one) and
activated these settings:

- MTRR mode discrete
- enable software memory hole
- disable hardware memory hole

and voila, got me 6144MB of RAM:
Memory: 6158992k/8388608k available (2669k kernel code, 131712k
reserved, 1001k data, 196k init)

disabling the hardware memory hole is mandatory, otherwise the kernel
wont boot, probably because it cannot access memory-mapped PCI I/O.

thanks again,
