Unfortunately with the latest Catalyst 11.8 drivers it still crashes with an 'EXCEPTION_ACCESS_VIOLATION'. It's probably because the netbook uses an AMD APU (Accelerated Processing Unit), basically a CPU with an integrated GPU. It also has a maximum resolution of 1024 x 600 where as the game wants to be 1024 x 768.
*shrugs* Oh well, I'll just have to stick with the desktop.
Thanks for the replies.
EDIT: Just out of interest I was trying to run it on an MSI U270 netbook. It runs Half Life 2, Torchlight, Heroes Online, Star Trek Online, Eschalon: Book I and Minecraft in full screen and windowed mode just fine. Eschalon: Book II is the first game I've had any problems with so far.
EDIT 2: Definitely a resolution thing. I plugged an external 1280x1024 monitor in to the netbook and the game worked fine at that desktop resolution setting. It obviously just doesn't like the 1024x600 setting.
