This seems to be a neverending topic. The hammerfall cards want a different format, which is currently not supported by pd's ALSA code. It might be possible to use ALSA's plugin device to do on the fly conversion, but I am not sure if the latency is better than with jack.
For the rest, if people with a hdsp promise me to test it I could change the ALSA driver to work with the hdsp. I do not have such a card myself.

OSS-emulation or Jack. I would recommend going these routes, rather than fighting with ALSA.
its no so much a fight, ALSA is just left in the dark, and you need to give it a flashlight - if youre up for the task you might want to add an extended alsa-options flag to the pd argv list, since usually its just not trying to talk to the soundcard in its preferred format (16int, 24int, 32bit ieee, etc). it is pretty redundant to use jack between pd and alsa solely to have more explicit alsa connection parameters at your disposal..
