About hammerfall DSP in linux:

Try booting windows and rebooting to linux, to keep the firmware uploaded. Make sure the host-error led does not flag. At that point it may have a very similar interface as the original hammerfall. It may also not be the case. I didn't try it.

I don't get very good latencies with the rme hdsp in win2k. 30 ms at 96kHz is barely usable with almost no cpu load. ASIO drivers may solve this under win2k, and that can't be far away since ASIO is available in portaudio and pd uses portaudio already.
