Have you tried configuring it like a ThinkPad 600E? That means using
ONLY "device pcm0 at isa? irq 10 drq 1 flags 0x0"
Do NOT use "device csa" 
and do not using "options PNPBIOS". 

Finally, you have to patch /sys/conf/files slightly:
Delete the line:
dev/sound/pci/csa.c     optional pcm pci
and edit the next line from:
dev/sound/pci/csapcm.c	optional pcm pci
to:
dev/sound/pci/csapcm.c  optional csa pcm pci

Be careful of the line to delete. It's the second lime for csa.c.

I'd send a patch file, but the location varies with the version of FreeBSD.

Rebuild the kernel and see if it fixes things up. It does the trick on
the 600E.
