glColorTableExt and ATI Radeon 7500

Sorry for my “maccheroni” english
I have a Ati Radeon Mobility 7500 on my Asus L3562 notebook.

I use this PC for GIS 3d program “Terranova 3d” (similar to a CAD program).

This program requires drivers with support of glColorTable Extension, but
with ASUS drivers (7.69) i have the error message " glColorTable Ext not
supported!".

With a Nvidia graphic board i don’t have any problem and the program run
perfectly.

It’s possible to solve my problem?

Thanks!
