Hi,

I got a NULL pointer dereference when moving my mouse around just a bit earlier
with gpm...

Unable to handle kernel NULL pointer dereference at virtual address 00000000
current->tss.cr3 = 00780000, %cr3 = 00780000

This was more or less a one-time deal, b/c I just used gpm to submit that right
now. In fact, all that happened was gpm died, and I restarted it with no
problems. Haven't rebooted yet.
