I wrote a little C programm for this for zaurus pda. It has no 
touchscreen suppport, but you might find
it useful:
http://git.linuxtogo.org/?p=thesing/kexecboot.git;a=summary
It works as follows:
-read available filesystems from /proc/filesystems
-read available partitions from /proc/partitions
-try to mount each partition, search for zImage in /boot
-present menu
-kexec choice

Here is a (bad) picture of it:
