New Debian Install: Console Problem

Hello Everyone,

I recently picked up a used HP Omnibook 4150 laptop and have installed Debian
stable on it. The problem I am having is that while I am running X at 1024x768
resolution, the console seems to be at 640x480 -- or something similar. It
seems this way becaues it is only using about half of the laptop screen. So,
the laptop screen is 14.1 inches across, but the console display is only 7
inches across.

Does anyone know how to fix this?

Thanks,

julian
