can't get dell E772p to display at > 640x480

["Robert P. J. Day" <rpjday mindspring com>]

  i'm sure there's a simple answer to this, but i just casually tossed a
copy of fedora on someone else's system -- intel 865G video card,
dell X772p monitor -- and it installed nicely, only to come up in (ugh!)
640x480.

  no problem, thinks i, a quick "redhat-config-xfree86", select 1024x768,
and we're all set.  nope.  still 640x480.  ok, check /etc/X11/XF86Config,
manually put in the "1024x768" as the only possibility.  still no change.
argh.  back off and at least see if 800x600 works.  nope.

  so i'm definitely puzzled.  i don't have the docs for the card or monitor,
but i *have* to believe this monitor can do better than 640x480.  i'm
about to dig into bugzilla, google, etc. to see what i can find, but does
anyone have a suggestion?  i've never seen a system so adamant
about a particular resolution.

p.s.  i have next to zero experience with intel video cards, so maybe
there's something blatantly obvious i need to do?
