For what it's worth, I'm seeing a similar thing intermittently on my laptop
running 2.6.34-rc5-mmotm0428.  It will about 50% of the time boot with
caps-lock set, but hitting Shift or Caps-Lock key won't light the corresponding
light (but it *does* actually change state).

Really sucks when the first thing you need to enter is the encryption key
for the disk.  Try twice, hit caps-lock, have it work. Of course, the key is
masked, so you can't tell which way it's set.

Problem resolves once the X server starts up.
