Yeah LTSP uses XDMCP, which is a special case for VirtualGL. See http://virtualgl.cvs.sourceforge.net/viewvc/*checkout*/virtualgl/vgl/doc/index.html?revision=1.68.2.39&pathrev=stablebranch_2_1#hd007006
for further information. The basic crux of the problem is that, if you just launch vglclient from within the XDMCP session, it will run on the server, not the client (which isn't what you want.) My guess as to the nature of this problem is that the X server running on the client machine lacks the XFree86-VidModeExtension extension (you can confirm this by running xdpyinfo.) As to why it lacks this extension, I have no idea.
