Yes, but can you get it to work at 1440x900 or similar resolutions
(unless you don't have a widescreen LCD, anyway)?  1280x1024 is a VESA
mode, and the system will let you do those if it doesn't otherwise
recognize the hardware, but you can't use widescreen modes, or
resolutions much higher than that.

For the record, I don't believe the problem is FreeBSD or X.org.  I've
got both an Acer and a Samsung that I've attached to a couple of such
systems: 6.2-STABLE/X.org-6.9.0 with a Radeon 9200 (which the radeon
driver is listed as supporting, unlike the X550), and
7.0-RELEASE/X.org-7.2 running on vmware with the vmware driver. All
those combinations work fine at the 1920x1200 max resolution of the
monitors.
