Why an OSS driver and not ALSA? OSS is deprecated.

From my POV, because I havent got time to port it to ALSA yet ;-)

from another POV, because ALSA is broken on ARM (or was), and other
platforms, wrt the mmap() operation mode. this makes it a bit pointless
to port a driver to thats mainly used for arm based PDAs...

It's now also used on MIPS and x86 platforms, in PDA, Cell phone and POS
applications.

I will be speaking to the ALSA list when I return from vacation about
the possibility of a similar plugin architecture for AC97 codecs.
