  well, i ugraded the bios to what is apparently the latest version
and that didn't solve the problem so here are the symptoms.  as i
said, the 3.0.0-13-generic kernel seems to work fine.  when i tried to
boot 3.0.0-14-generic, the system froze almost immediately, so i
booted in recovery mode and could see the final line of the form:

  ... generic-usb ... Dell USB keyboard

then nothing.  so the final operation of that kernel was to recognize
my USB keyboard.  same thing with 3.0.0-15-generic.

  just in case it was the external keyboard that was causing the
problem, i unhooked both keyboard and mouse, at which point booting in
recovery mode gave me a final printed line of:

  Begin: Running /scripts/init-bottom ... new high speed USB device
number 5 using ehci_hcd

and that's it.  more interestingly, when i tried booting in recovery
mode with my hand-rolled 3.3.0-rc7 kernel, it got as far as:

  Begin: Running /scripts/init-bottom ...

and that was it.  and when i went back to the working 3.0.0-13-generic
kernel, right after that line about running init-bottom (when booting
in recovery mode), i got:

  done.  hostname start/running.

and a shell prompt shortly thereafter.  so there's something funny
going on with USB, it would appear, but i'm open to suggestions as to
what to check next.
