if they not supported, nothing you can do. only software rendered with Mesa (http://www.mesa3d.org/) then.
if you are under mac or win see this (http://www.realtech-vr.com/glview/) to know what is supported and what not.

You can find directX 10 (openGL3.0) hardware at 50 / 60$.. and openGL 2.1 HW cost nothing. If you are not on a palm I think that it's a driver problem.

The problem is that I read somewhere that these extensions can be supported by opengl 1.4!!

"can" is the magic word here but apparently yours cant. find some demos using this extension and try to run them on your hardware.

That's what I did... I've tried some demos and they didn't work... It seems that I have to upgrade my hardware... Thanks guys for your help..
