  Using the boot loader parameter vga=791 should configure your video card
to run in 1024x768 mode with 16-bit color.  A few examples of VESA video
modes (or VGA codes) are shown in:
    http://fedoraproject.org/wiki/Fedora7/FAQ#head-1d333d02c2c2e2f3b06d18ce92d41dcbba823d59

with more information elsewhere, e.g.:

  http://en.wikipedia.org/wiki/VESA_BIOS_Extensions#Linux_video_mode_numbers

However, in f8, you may be rewarded with something like:
-----
Undefined video mode number 791
Press <ENTER> to see video modes available, <SPACE> to continue, or wait 30 sec
[<ENTER> displays something similar to: ]
Mode:    COLSxROWS:
0  0F00   80x25   VGA
1  0F01   80x50   VGA
2  0F02   80x43   VGA
3  0F03   80x28   VGA
4  0F05   80x30   VGA
5  0F06   80x39   VGA
6  0F07   80x60   VGA

If so, you may wish to add your experience to:

The good news is that for your purposes of the moment, trying mode 6 from
the list shown above may meet your needs of just packing more information
on the screen.

Cheers,
