If you have a kernel compiled with PCVT you can easially halt your system.
Easy. Compile a kernel (I assume this is limited to i386 unless PCVT is compiled on other platforms) with PCVT support instead of the pccons driver. Boot off it. Hit ctrl-alt-esc. The result will show on ttyv0.
Don't know. However, I think limiting the possible values that PCVT gets to change terminals would be a way.
