>Description:
On Dell Lattitude CPxJ the VESA console blanks after a short period of 
inactivity and does not unblank.

The screen is completely blank and non-lit.

It is possible to unblank by activating the system bios.

It is possible to type commands while the screen is blank.

Typing while the screen is not blank seems to prevent blanking.
>How-To-Repeat:
compile kernel with vesa console

boot
