I'm assuming you're running squeeze, not lenny.

No idea why VT switching doesn't work for you. To get Ctrl+Alt+BS working
again you need to change /etc/default/keyboard:

XKBOPTIONS="terminate:ctrl_alt_bksp"


If you have Magic SysRq enabled in your kernel (IIRC the default Debian
kernel does), you can use that instead of reset the next time you need
it. Press:
AltGr+SysRq+S (SysRq=S-Abf on a german keyboard) to sync disks,
AltGr+SysRq+U for emergency unmount of all file systems,
AltGr+SysRq+B to reboot or AltGr+SysRq+O to power down (on many systems
only one of B and O works).
There are more key combinations (see Documentation/sysrq.txt in the Linux
kernel source), but these are the most important ones.
