 That's what I'm going to try.  Is there any archive of snapshot
 kernels, or do I need to pull in lots of source trees?  (Btw -- as of
 yesterday, I can't even suspend.  For that matter, I can't even boot
 -current kernels unless I disable ugen, the fingerprint reader.  I
 wonder if that's related.)
