Uhm, no. The real problem is this:
linux_sysent.c: { AS(reboot_args), (sy_call_t *)reboot }, /* 88 = reboot */
We can't do that, we need a "linux_reboot" function which interprets
the arguments and does not reboot the machine when the call attempts
to change the "Ctrl-Alt-Delete" setting. I'll dig up my patch after
Thanksgiving and commit it.

This may also be true, but is orthogonal to the reboot issue.
