..nice troll, unless you meant the pxe version, I haven't tried that,
only the common kexec on rt-amd64 and rt-i686-pae kernels on boxes,
so, 'aptitude install kexec-tools' and try 'reboot' again: ;o)
arnt@celsius:~$ apt-cache search kexec
kexec-tools - tools to support fast kexec reboots
petitboot - ncurses version of petitboot, a kexec based bootloader
petitboot-twin - Twin GUI version of petitboot, a kexec based bootloader
pxe-kexec - Fetch PXE configuration file and netboot using kexec
arnt@celsius:~$ man -k kexec
coldreboot (8) - Force a cold reboot bypassing kexec-tools default
kexec (8) - directly boot into a new kernel
kexec_load (2) - load a new kernel for later execution
pkexec (1) - Execute a command as another user
pxe-kexec (8) - Read PXE configuration file and kexec entries
> doesn't support an amd64 kernel.
..maybe, kexec boots rt-i686-pae ok on my eeepc:

Scenarios always come in sets of three:
best case, worst case, and just in case.
