It looks like this might be a kernel incompatibility.  I get the same
problem when trying to compile against 2.6.12, but if I try to compile
against 2.6.18-rc4 it works.

The only thing that seems strange to me is that the first error is because
struct snd_sg_buf isn't defined.  In 2.6.12, this _is_ defined in the
kernel file include/sound/memalloc.h, and bt87x.c _does_ include this file.
It's no different than 2.6.18-rc4.

So it should work under 2.6.12 (and 2.6.13 too I would assume), but
doesn't.  I'm not sure what is going on.  Something to do with include
searching maybe?
