If your card is supported by SVGATextMode, then simply install this and
use it. Otherwise you can use the program mode3 from a recent svgalib
distribution to set the mode (run mode3 788). You will still need to
somehow tell the kernel (and maybe user space) that the console size is
different. I use the following kernel module: (a kernel module is a must
if you want to have different sized consoles. This functionality exists,
but is not visible to user space).
