T60 question about video memory

[themetabaron]

I have a T60 Type 2008-CTO 1.83 Core Duo T2400, 2GB of Ram with a 14" LCD and ATI X1300 video card. What's really puzzling me is that when I check the video in properties it shows 512MB of video memory, see link to screenshot below.

How is that possible? Do these cards actually have 512MB or this Windows being silly again?

I have always thought the max amount of video ram was 256MB on some T60P/T61P configurations, I just don't get it.

Thanks in advance.
