Well, I did a little more digging into my gdb problem.

I'm not sure if the new toolchain stuff is completely alpha core-dump
savvy.  When using the symbols out of the kernel, it ends up making the
wrong decisions about when the stack frame ends.  Also, I think that since
in this case I'm getting a kernel trap, it doesn't quite know what the
saved state of a kernel trap is, since (when I use it) it's actually missing
a frame.  But after banging on it a bit, it gives me as much of a traceback
as it did without symbols, so I call that an improvement :-)

In case anyone's interested, a patch is appended.

A lot of people asked me about AFS for NetBSD/Alpha.  If I get it working,
then I'll make an announcement.  Otherwise, assume that I've crashed and
burned like better people before me :-)

(Current status -- creates local disk cache, mounts /afs, but cannot talk
to vldb servers.  Simple pioctls (like setpag) work).
