I think I have stirred some interest in this on the emu10k1 list..  The
SBLive cards are capible of quadrophonic sound (in fact that's their
purpose) and there is a nifty hack to make /dev/dsp do front and /dev/dsp1
do rear.  In the absence of a quadrophonic device driver and defined
interface, the idea was to set up the hack and make OpenAL use it if it
doesn't already.

This would be sub-optimal, but it would be enough to get apps to start
using the library which will cause more people to have the itch to make it
work with hardware accelleration, etc..
