Yes, PCI bus power saving is off and sound using the ALSA driver works.

Oh, interesting. I have added scripts to unload/load modules when
suspending/resuming.

But it seems the question remains: Have anyone got the 2.2.17 sound support
working, or should I post a bug report to the maintainer?

BTW: I didn't compile sound support in 2.2.17 as a module, I compiled it right
in, just like I used to do with my old laptop (which had a Soundblaster chip).
