 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.
