Works M-sysrq on this machine? If you have a kernel compiled with
support for it (standard Fedora kernels have it), then check
/etc/sysctl.conf, set "kernel.sysrq = 1" and do a "sysctl -p"
afterwards.

An overview over the commands you can use is here:

Maybe Alan could give you better advice what to do here..
