Some more option to reboot:
Two issues: screen and keyboard
For restoring the screen, first kill X, and then run a program that
restores the textmode. Svgalib comes with three such programs -
restoretextmode - uses svgalib to set the mode, and requires that you
saved the text mode (using savetextmode), before.
mode3 - uses real mode vga bios of the card to set mode 3.
vga_reset - uses real mode card init routine from card bios.
The order is in increasing chance of the program working, but also in
increasing chance of crashing the computer.
It is also possible that the card is in such a state that only a
hardware reset will get it out of.
(Someone wrote an improved version of vga_reset, you might find it on
freshmeat, or google).
keyboard: it is possible that the console is left in raw mode. To
restore to cooked mode, either use Alt-SysRQ-R (if enabled), or run
kbd_mode using telnet/ssh.

Can't help with the real problem.
