i tried to use the pcmcia-cs driver again (2.4.24-ck1 ... they didn't
work with the hdsp, either (afaik, the pcmcia-cs driver never worked
with the hdsp, but i'm not sure about that)
the dmesg output was:

PCI: Found IRQ 5 for device 02:00.0
PCI: Sharing IRQ 5 with 01:00.0
PCI: Found IRQ 11 for device 02:00.1
PCI: Sharing IRQ 11 with 00:1f.3
PCI: Sharing IRQ 11 with 00:1f.5

ALSA ../../alsa-kernel/pci/rme9652/hdsp.c:5031: unable to grab memory

RME Hammerfall-DSP: no cards found

i have no idea of the differences between the cardbus drivers of the
kernel and of the pcmcia-cs project ...
anyway, the hdsp is working on a certain area of memory, that the
pcmcia-cs driver can't grab the kernel driver can ... 
i disabled acpi and apic and used pci=biosirq as kernel flag

maybe this can give you a hint ... anyway, i hope thomas can comment on

cheers and thanks for your help...

mad to talk, mad to be saved, desirous of everything at the same time,
the ones who never yawn or say a commonplace thing, but burn, burn,
burn, like fabulous yellow roman candles exploding like spiders across
the stars and in the middle you see the blue centerlight pop and
everybody goes "Awww!"
