Some of the Xp drivers might work for Windows 7
That might be risky. Windows 2000 and XP share a similar kernel so I've seen many Windows 2000 drivers work in XP. With Windows Vista, Microsoft came with a new kernel and 7 is just an evolution of that. I've seen many Vista drivers work in 7. But from XP to 7 it's a long stretch with more risks that the drivers won't work or cause problems, but you can always try. Personally, I'd try to search for generic drivers for Windows 7 if you can find some that work, for instance if some chipsets are missing, check on the Intel website if you can find generic ones for your generation of chipsets. But with laptops most manufacturers have custom ones so it's no guarantee you will find some that work.
