Reinstalled Vista on Laptop, now no FN keys work

[QueBert]

This is a gateway I'm fixing for a friend. Their Vista borked and they didn't have the recovery disc so they bought an OEM copy off Newegg. Gatways site has a whopping 3 drivers for this. There isn't one for the FN keys, and unless I'm doing something wrong Vista doesn't have support for them built in. What the hell do I need to do here to get the function keys working?

*edit*

n/m I fixed it, had the wrong version of the chipset drivers doh.

I think you have the wrong chipset drivers.
