OK, so yours is definitely using the ALSA standard assignments in 
hardware and Mark's is using a card-specific assignment in hardware.

So, the behavior we should see on yours if Mark wrote the patch to use 
the outputs for his card:

Your mappings (hardware and drivers):

chn0 - front left
chn1 - front right
chn2 - rear left
chn3 - rear right
chn4 - center
chn5 - lfe

His card's hardware mappings (which would then correspond to the 
software mapping in Myth):

chn0 - front left
chn1 - front right
chn2 - center
chn3 - lfe
chn4 - rear left
chn5 - rear right

So, you should hear the center channel on your rear left speaker, lfe on 
your rear right (assuming your speaker has the range), rear left on your 
center, and rear right on your lfe.

This seems to agree with your description of the issue...
