Reformatting to WINXP (NEED WLAN DRIVER) - Please help

I've just reformatted my Acer Aspire One (D257) from Windows 7 to Windows XP. I've found drivers for all my hardware except one, my WLAN. Through searching the model number on the netbook's sticker, I've ascertained that the wireless network card loaded is an intel centrino wireless-n 100. After much exhaustive searching I am quite worried now that this model has no Windows XP driver??? http://www.intel.com/support/wireless/wlan/sb/CS-031641.htm

Please help me find a driver that will enable my hardware to function on XP. If the appropriate one does not work, perhaps there is some workaround or other compatible driver software? I'm desperate, this light laptop is almost nonfunctional under Windows 7, so reverting to the factory OS is not an option. For reference here is the acer support page, which would provide me with the perfect drivers if only I was running W7. http://support.acer.com/us/en/product/default.aspx?tab=1&modelId=3659

Thanks!
