rme hammerfall dsp questions

[Karl Grill <kgrill@chello.at>]

Hi all,
I'm working on getting the hammerfall dsp rpm to work under alsa. 
Unfortunately, I haven't experienced the proverbal supportiveness of RME 
towards linux yet (my e-mails have gone unanswered for three weeks now),
so I'm using a disassembly of the windows (2k) driver (to Paul: yes, maybe
I'm insane). By now, I know the card detection routine, and it is a bit 
different from the one that is used in the alsa driver (apart from the 
fact that it has to deal with the additional case of the RPM), 
apparently the definition of some of the bitfields in the control 
register has changed. This, in turn, seems to be due to the new 
firmware, and as there is no old firmware for the RPM (it is only 
supported by the win2k driver, and the alsa driver seems to be modeled 
after the w9 software), I'm afraid that adding RPM functionality means 
that I will have to adapt the driver as a whole to the new firmware. But 
maybe it's not so bad, so here's my question:
Does anybody have any experience with using (or failing to use) any of 
the dsp cards with the new firmware (or only with the new firmware for 
the pci/cardbus interface of the multiface/digiface) under alsa? Or 
would any of the digi/multiface users out there to be willing to try the 
new firmware on their cards (I think there's little risk involved, 
except that in the case of failure, you will most likely have to do a 
cold boot or two).
Regards
kg
