[PATCH] pmac: sound support for latest laptops
This patch hacks the current Alsa snd-powermac driver to add support for
recent machine models with the tas3004 chip, that is basically new laptop
models. The Mac Mini is _NOT_ yet supported by this patch (soon soon ...).
The G5s (iMac or Desktop) will need the rewritten sound driver on which
I'm working on (I _might_ get a hack for analog only on some G5s on the
current driver, but no promise).
