James,

As the code is written, you're out of luck.  For better or worse, reboot and 
power off have been handled identically since ... forever.

If you want to hack it yourself, you can probably get away with the following:

"Correct" way:
- Add appropriate CONFNAME_REBOOTSCRIPT and CONFVAL_REBOOTSCRIPT_DEFAULT macros 
to conf.h.
- Change CONFNAME_POWEROFFSCRIPT to CONFNAME_REBOOTSCRIPT in powerOps.c for the 
reboot case.
- Define your own handler for "reboot-vm".

Quick'n'dirty way:
- Hack System_Shutdown in systemLinux.c.

Hope this helps.
