I've got one of the new MacBooks, and I'm running Windows XP, SP3 on it. It's got the 9400M graphics chipset on it, and it's got 512mb of ram on the card, but SETI@Home reports it as only having 253Mb of ram. Any idea what's up? I've got another computer with an 8800 card in it with 512MB of ram, and it reports the full memory amount. I'd like to get CUDA work on my laptop going, but I'm stymied here... anyone else running into this issue?

I see you've already asked this question in Number Crunching and have subsequently received some possible answers.

Yep.. but thus far, nothing's turned up an actual solution. Somewhat stymied still. *sigh*
