I had the displeasure of digging around in gdb config recently, so
while I'm far from an expert I think I know what's wrong.

It looks as if you need to add a call to bsd_kvm_add_target() to
_initialize_alphabsd_nat() at the bottom of
src/gnu/dist/gdb6/gdb/alphabsd-nat.c, akin to the one in
i386nbsd-nat.c.

To do it properly you also need to add bsd-kvm.o to NATDEPFILES in
src/gnu/dist/gdb6/gdb/config/alpha/nbsd.mh, and rerun mknative in all
its full glory.

mipsnbsd-nat.c and config/mips/nbsd.mh also appear to be missing this,
and maybe other targets too.
