There's a block of code in soundcard.c that has a lot of #ifdef's that
uses a 4k buffer size for FreeBSD.  I'm pretty sure that the version I've
compiled is using a 4k buffer to, but I'll take a look at that.

Didn't really have to change much, just a few things to get it to compile.
I got the driver from ftp.cdrom.com:/pub/FreeBSD/FreeBSD-current/src/sys/i386/
isa/sound (just tar up the whole directory); then you also 2 include files
from src/sys/i386/include (soundcard.h and ultrasound.h) and src/sys/conf/
conf.c.

As soon as I get the "cut-off" problem fixed, I'll upload the source and
some instructions on how to hack it into the kernel to some site.
