Same laptop, rebooted into XP 32-bit, same issue on VMWare Server 1.0.10, 32-bit or 64-bit Ubuntu 9.10, installer just doesn't behave well.

I will admit I have one oddity: I have to disable multi-core rendering in Half Life 2-based games or my machine stutters horribly, so it might be correlated to that, but that's all I can personally think of.
