IBM SK-8815 With Lenovo W510

[Annorax]

I have a Lenovo W510 running Windows 7. I also have an older USB IBM SK-8815 keyboard that I would like to use with it. When I plug it into the laptop, everything works fine (even the volume and forward/back buttons) but the program hotkeys (Calculator, etc...) do not work.

I've been looking for a driver for this keyboard but without any luck. Googling around reveals some results but from some seemingly shady websites. This official Lenovo driver below is the closest thing I could find from an official IBM/Lenovo site.

Does anyone know where I can get a driver for this keyboard? Or, just any way to customize the hotkeys.
