I dont think that the problem has anithing to do with the interaction betwen alsa and pulseaudio,
ists alsa or the kernel module, it seems that the module used with the kernel 2.x was "external" and from another
Programmer as the module which is shipped with the kernel 3.x .

You could try the above with the file /usr/share/alsa/cards/USB-Audio.conf
It seems to be the file which contains the profiles for the channel assingnment.

another thing you could try would be this:
https://wiki.archlinux.org/index.php/PulseAudio#Pulseaudio_through_OSS
maybe it works trough the oss emulation of alsa.
