Mike,
HDMI really supports multi-channel PCM. I am not sure, though, if all receivers support it, and if the Linux drivers of all video card brands support it. I have a Denon receiver and an Intel IGP, and it works nicely out-of-the-box under Ubuntu since 11.10. I just need to select the appropriate output in the sound control applet.
Of course having a52 would still be nice for people without such hardware.
