Ben-

The 3c575 is Cardbus and FreeBSD (neither -stable nor -current) supports
cardbus (this is coming down the pike).  Apparently, there are some
hacks available that _might_ allow you make this particular card work.

The relevant patch is available off of 

http://www.advogato.com/person/imp/

In the interim any of the single-function (non-combo) venerable
3c589 cards ought to just work.

I would strongly recommend against using anything other than "-O -pipe"
for building both world and kernel.

The sound should work (sort of .. man 4 pcm).  You do need to do a

cd /dev; sh MAKEDEV snd0

The Crystal CS423x are PNP ISA sound cards, so the trick is adding

options PNPBIOS
device pcm

to your kernel.  The CSA is the bridging code for the Crystal PCI
sound cards (eg Cold Fusion that are in the 570's and newer 600's).
