You can not use dlopen from loadable modules.  Use the xf86Loader interface, 
which is documented in programs/Xserver/hw/xfree86/doc/DESIGN (section 17.4), 
and refer to the glide(4) driver for an example.

Yes, we've changed module formats in 6.9.  If your server was using libfb.so, 
dlopen would have magically worked, but you should still use the Loader 
interface.
