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
that...

cheers and thanks for your help...
