hiho,
my problem is solved! i get help from an kernel developer.
he told me that there is a problem with no fast enough interface initialisation. so the
kernel will load the driver before the card is rightly initialised. also he told me that
the patch from tim blechmann probably works against this problem.

@tim i don't try your patch sorry, but it's sound like you hit the problem.

i use this workaround for the moment:

* boot the kernel
* plug in my cardbus-interface and see the error mesage

        RME Hammerfall DSP 0000:16:00.0: enabling device (0000 -> 0002)
        RME Hammerfall DSP 0000:16:00.0: PCI INT A -> GSI 16 (level, low) -> IRQ 16
        Hammerfall-DSP: no Digiface or Multiface connected!
        RME Hammerfall DSP 0000:16:00.0: PCI INT A disabled
        RME Hammerfall DSP: probe of 0000:16:00.0 failed with error -5

and than the workaround...
* rmmod snd_hdsp
* modprobe snd-hdsp
that's all... easy :))
after reload the driver the cardbus-interface load the firmware correctly

for all other people with the same problem
my system is currently:
thinkpad r61, multiface 1 connected over the small (old) pcmcia cardbus-interface.
kernel 2.6.29-rc6 + the brand-new rt patch (thx :-) for this kernel. and the kernel included alsa-driver.
alsa-firmware-1.0.19
alsa-tools-1.0.19
maybe it also will work with older versions of firmware and tools. i don't test this.

greetings wolke
