Some (or many, depending on who you ask) laptop brands have pretty faulty ACPI tables. WindowWindows XP was very lenient with those kind of things and handled many things on its own even if they were not correctly specified. But Vista started to adhere to them more precisely which is nice if ACPI is correctly done in the hardware but downright sucks if it isn't. Hardware vendors weren't quite forced to look after these things because they somehow worked.

A BIOS upgrade might solve this, but in many cases there is no easy solution (short of reinstalling XP again) because the vendor already got all the money they are going to get from you so why should they care?

A friend of mine had an issue with his ThinkPad T40p where the fan would only kick in after the CPU reached around 95 °C which was not a nice temperature to keep the laptop on your lap.
