They can share. My line from pciconf is 
pcm0 at pci0:2:7:  class=0x040100 card=0x030013f6 chip=0x70121039 
rev=0xa0 hdr=0x00

It knows mine is pcm0 and we have a different card number. I don't know 
if that is important.

Probably not unless you can program. You have to go through the kernel 
modules and find which sound module handles the SiS7012. That is where 
the maintainer comes in and I don't have any idea who that is right 
now.

I have never looked at the sound stuff. It has been a sort of black 
magic that worked. I also have a -current machine that won't do the 
installworld and it has my attention right now :(.

If you do a find from /usr/src. For the lack of a better idea, I just 
used sound. You will see something like

# find . -name sound -print
./sys/compile/TOPAZ/modules/usr/src/sys/modules/sound
./sys/dev/sound
./sys/gnu/dev/sound
./sys/gnu/i386/isa/sound
./sys/i386/isa/sound
./sys/modules/sound

Your problem is buried in there somewhere. I think you can ignore 
the ../gun and ../isa. TOPAZ is the name of my kernel and the kernel 
config moved the code that handled  SiS7012 in there. TOPAZ/.../sound 
has 3 directories, driver, pcm, and snd. I assume that your 7012 
handling code that doesn't recognize your module will probably show up 
in one of them. 

You can use http://www.freebsd.org/cgi/cvsweb.cgi/ to track who did the 
last work on the module with the SiS7012 in it. They will be your best 
bet on getting sound.

I don't what sound cards run where you live but I can buy really cheap 
pci ones "that work" for under $20 USD. They are usually as good as the 
integrated ones if not better. It all depends on the import duty and 
how long you can deal with a computer and no sound :).
