Bug Description

I was doing the following when X crashed:

* I was running WinXP in Virtualbox with very heavy hard drive activity while on battery
* As I got the "Battery critically low" message, I plugged in AC, but apparently gpm did not recognize the plugging immediately
* So my laptop suspended (because I had configured that way) while running Virtualbox and heavy HDD (and possibly CPU) load
* After resume, I got thrown into VT1.
* I switched manually to VT7, and moments later a new X server started on VT8; after logging in, I got the apport crash handler.
