Graphics chips in laptops

Hi,
Just wondering if anyone has any experiences or thoughts to share about
graphics chips in laptops. In particular, I’d like to know what the
chances are of getting, say, a Radeon 9700 Mobility chipset working
under QNX. The desktop version of the card is supported, but is the
laptop version compatible, or is it similar in name only?

Any recommendations for laptops (preferably still available new) which
are highly compatible with QNX 6.3 would be appreciated too. Basically I
would want accelerated video, sound, USB, ethernet, and PCMCIA to work.

Cheers

Garry
