!!  That's a pretty major regression in my opinion; I've never yet
myself run into a NetBSD version which doesn't support booting kernels
under more-or-less arbitrary names.

Thought: could this be related to some code I saw mentioned for
treating directories (containing kernel and modules and maybe other
stuff) as if they were kernels?  I've already run into one situation
where booting success depends on...something like that.  (Specifically,
when PXE booting i386 and/or amd64, I find that it fails with "boot -s"
but works fine with "boot netbsd -s".  Still haven't tracked it down.
May well be related to one of my 5.2 patches.)

It might be interesting to objdump them with the option to disassemble
instructions (-d, I think?) and then diff the results.
