Description of problem:
xorg improperly gives a display of "1920x1440". Should be "1800x1440". Selecting 1920x1440 gives me 1800x1440 display however.
Version-Release number of selected component (if applicable):

1800x1440 isn't in xf86config.XF86SupportedResolutions() which is used
by rhpl.xhwstate which we use in system-config-display. However DDC
shows your monitor supports it but not the resolution we mistakenly set

Fedora Core 3 is now maintained by the Fedora Legacy project for security
updates only. If this problem is a security issue, please reopen and
reassign to the Fedora Legacy product. If it is not a security issue and
hasn't been resolved in the current FC5 updates or in the FC6 test
release, reopen and change the version to match.
Closing per lack of response to previous request for information. This bug was
originally filed against a much earlier version of Fedora Core, and significant
changes have taken place since the last version for which this bug is confirmed.
Note that FC3 and FC4 are supported by Fedora Legacy for security
fixes only. Please install a still supported version and retest. If
it still occurs on FC5 or FC6, please reopen and assign to the correct
version. Otherwise, if this a security issue, please change the
product to Fedora Legacy. Thanks, and we are sorry that we did not
get to this bug earlier.
