Re: "sync out of range" in textmode after leaving X (or in VCs)

i fixed this problem, as root, by editing /etc/lilo.conf, then running the command lilo.

in particular, i changed
  vga=791 
to
  vga=795
then ran lilo.

appearantly, 791 was fine for my 1024x768 panels
but a different value is need for 1280x1024 panels

here is a table that i ripped off from 
http://www.uno.edu/~adamico/banshee/files/vesafb.txt

  Colours   640x480 800x600 1024x768 1280x1024 1600x1200
  --------+---------------------------------------------
  256     |   769     771      773      775       796
  32,768  |   784     787      790      793       797
  65,536  |   785     788      791      794       798
  16.8M   |   786     789      792      795       799

there remains a problem.  it is the same problem that i
had with my 1024x768 panels.  whenever i leave X, the 
first 4 columns of texmode are shifted off the screen
(the whole screen is shifted to the left by four columns)
this is not the case upon a cold boot, but only with textmode
of VCs or leaving X.
