Can't tell you either.

Sorta - it also depends on color depth. For example, at 1024 x 768, you
are scanning 786432 pixels, and would need that many bits for "black
and white", about 394 kilobytes of RAM for 'four bit color', and some
1.2 Megabytes for 24 bit color (256 shades of each primary color), and
so on.

My preference when dinking about with hardware in the lab is to ALWAYS
start Linux in the text based mode, so that I can gain information before
trying to get X to run.  If you are unsure about this (and using LILO as
a boot loader), see the BootPrompt-HOWTO, and look at the vga= option.
