  There are two set of constraints...

  1) See the page http://koala.ilog.fr/cgi-bin/nph-colas-modelines which
can generate custom modelines for you system.  You need to know the max
and min frquencies (horizontal and verticl) for your monitor.  I've
managed to get 2048x1536 running on my NEC Multisync95... wheeeeee!!!

  2) You mentioned it was an ancient card.  How much RAM does it have?
Under X, here are the RAM requirements...
   8 bit colour (256 colours) => 1 byte per pixel
  16 bit colour (65536 colours) => 2 bytes per pixel
  24 bit colour (16777216 colours) = 4 (yes, *FOUR*) bytes per pixel.
A 1-megabyte video card will give 1152 x 864 at 256 colours or 800 x 600
at 65536 colours.
