The grub documentation includes provides kernel failover provisions, but

Should I expect this to work?

Is there some other mechanism to boot a
different kernel just once--on the next boot?

  My guide here has an example of using grub's savedefault --default X 
  --once directives in order to specify a kernel to boot next.  It tries 
  to boot that kernel.  If you reboot again, it falls back to the first 
  listed kernel in grub.conf.
  
 Hmmm, this syntax looks different from that in the grub docs on gnu.org.
 Thanks for forwarding this. I will study and see what I can do with it.
 I am precisely in the position of needing to manage a server which I
 cannot get to physically.

It is -- we've got a patch that implements this functionality, and we've
had it since before upstream had the ability to do this.  Nobody's filed
any bugs requesting the new way, and there's code using it, so we just
haven't migrated to the new way yet.
