Any other ways of reducing IGP system RAM allocation?

[mikeymikec]

The way I normally do it is to look in the laptop's BIOS settings to reduce graphics RAM allocation when the usage scenario wouldn't ever necessitate that amount of RAM for graphics. However on the Lenovo V130 a good 640MB or thereabouts is being allocated to the graphics and there's no BIOS option to change this. Is there any other way to do it?
