Vista causing a problem with XP?

I was not sure which forum to post this in, Vista or XP, so let me know if this needs to be moved. I recently partitioned my laptop and installed vista in conjunction with xp which i was already running. So now my system has 3 partitions, one for xp (C one for Vista and one for data. However, now when I boot xp the keyboard will not function at all sometimes. Other times it will run smooth. I have never had this problem before and only started after the installation of vista. I never have a problem with the keyboard when using vista. Does anyone know what could be causing this? The model I am using is a Lenovo T60 thinkpad and last time I checked the drivers for vista where not available yet. Also, the audio does not work in vista but does in xp, i know this is a driver issue but are there any known workarounds? Not really a big deal since the laptop is used mainly for school work.
