There was a buggy check once (in Marcelo's kernel directly after the PPC
merge) in dmasound_awacs.c, don't know if it is still there. The problem
was that pangea chipsets reported no revision number for Keylargo and the
kernel then wrongly reported that they could do hardware byteswap. It was
reported on this list and benh said he would fix it.
