video card performance

[T Molnar]

Anyone know if tiger or then next update will update the drivers for the
ATI mobility card in the 1 Ghz tibooks?

I looked around ATI's site found nothing of particular use.

Anyway to get better performance from this card.
I have installed radeonenabler to let me tweak stuff, but that
isn't a driver  update.

Any information or suggestions (other than buying a new machine)
would be warmly received.

thanks
