What are the names of some PCI video graphics adapter cards (if any)
that support Windows Server 2003?

For a specific video card (as example), see
http://www2.ztgroup.com/server_amd_4u.asp

According to 

http://groups-beta.google.com/group/microsoft.public.windows.server.general/browse_thread/thread/91f8ff54b6b67cfa/a3dc1ffdb3d03810?q=windows+server+2003+graphics+cards+supported&_done=%2Fgroups%3Fq%3Dwindows+server+2003+graphics+cards+supported%26hl%3Den%26lr%3D%26sa%3DN%26tab%3Dwg%26&_doneTitle=Back+to+Search&&d#a3dc1ffdb3d03810


video cards supported by WindowsXP (which means most of them you can
buy today) are also supported under Windows Server 2003.  (Expect do
manually enable video acceleration if neeed).
