Also it just came to my attention that if my receiver always sees the hdmi connection as stereo (apart from when using ac3/dts passthrough) channel remapping is not the solution, but somehow something else is messed up.
I think I should try some options in modprobe.conf for snd-hda-intel but I am not sure which ones, and from all the examples I can find on the web, it seems none of them are talking about a radeon hdmi connection...
So I'm asking for advice here again :)

Hi, I think there are developments in ffmpeg projects, to support multichannel passthrough through HDMI, ALSO only provides infra and interface to the HDMI. The passthrough decoding is handled by apps.
Here is the snippet from the ffmpeg's 'svn log' ------------------------------------------------------------------------ r25760 | cehoyos | 2010-11-17 20:22:59 +0800 (Wed, 17 Nov 2010) | 6 lines
Add support for IEC 61937 ("SPDIF") encapsulation for E-AC-3. Only works via HDMI.
Patch by Anssi Hannula (anssi d hannula a iki d fi), based on some work by myself. ------------------------------------------------------------------------
You can search in ffmpeg's development's mailing list for more information.
Thank you.
