Grant,
I downloaded the manual from here but it doesn't mention the graphics much. As feared, there's no mention at all of being able to fit another video board.
There's a section in the manual entitled "Selecting Display Modes" but that only seems to be related to using an external monitor.
I did find this in the troubleshooting section near the end: "On some VAIO models, the graphics memory is shared with the system. The optimal graphic performance in this case is not guaranteed." But it doesn't say whether that applies to your model, nor whether you can do anything about it if it does apply.
One other thought, maybe Trainz would run at its lower screen resolution setting. If you can get into the Trainz Configuration option, try reducing it to 800 x 600 instead of the usual 1024 x 768. This will greatly reduce the amount of video memory required. Sorry if you've already tried that. If you can't get into that option, then it's also possible to do it by editing the trainzoptions.txt file using the Notepad program. Add this command, on a line by itself, anywhere in the file:
-800
HTH, John
