If it was firmware, wouldnt that mean that XP should be limited to 64MB also?
I mean firmware that's different on Macs and other Windows PCs.... the firmware of video cards has been different in the past on PowerMacs (and one must reflash the firmware of the Windows ATI video cards to get them to work in a PM, even though it's the same chipset, AFAIK).
But what I mean is more like screen spanning, which is a video card thing, was disabled by firmware on iBooks in the past. Not by the video chipset manufacturer, but by Apple.
So I'm wondering, now, where the 64MB gets imposed -- if it gets imposed in firmware or in software. I haven't heard anyone report evidence that Windows is using more than 64MB for the GMA950 *on* a MacBook or Mac Mini, when booted in Windows. Is that true? That would obviously answer the question on the side of software (and not firmware). But if it's providing 64MB when booted in Windows, too, then it depends, doesn't it?
