I ran some more tests and found that ending a kde session was causing
/boot to be un-mounted. (running kdm 4:3.5.10.dfsg.1-2)
Attached is a quick hack workaround, as I could not figure out how to
determine where in the kde session logout /boot was being un-mounted.
In general, not all users will have a separate /boot partition and even
fewer will run into this problem, but perhaps a warning message could be
generated if /boot exists in /etc/fstab and /boot is not mounted when
kexec-load runs?
