Need x64 drivers


I'm going to hopefully be installing a tri-boot of XP Professional SP2 x64, 7 Ultimate SP1 x64 and Ubuntu 12.10 x64 fairly soon but I need some assistance in finding the XP drivers.

My system is an Acer Aspire 5738PG-6306. Acer's support site only has x86 drivers for this system line which won't help me lol.

I would be very grateful for any help here. I've never had to hunt down drivers elsewhere from the system manufacturer site so I'm kind of lost.
