Help install xp64 on a vaio CS series plz...

Hey
I am new here and was hoping you could help me...
I recently purchased a Sony Vaio CS17G ;
[ http://www.sony.co.in/product/vgn-cs17g (if that page isn't available,as it is now, the laptop has the same hardware as this http://www.sony.co.in/product/vgn-cs18gn except for the fact that the CPU is a P8400 instead of a P8600 and the absence of a fingerprint reader) ]

..in India. This is almost equivalent to the CS190 of America. I was trying to install xp64 along side vista to utilize the 4Gb of RAM available for recording music.
After looking, i found that on their official website in India, there are drivers available for download.

Now the thing is that as i'm on a newer laptop, i'll need to slipstream (not sure about how to go about this either) the drivers to the disc for the SATA hard drive (thanks to the reduced Insyde H2OBios). Now, i don't know whether these drivers are for Windows XP Professional 64bit. If they are for xp32 , does any one know where i would be able to find 64bit drivers?
Also, i guess it would be ideal if someone could show me how to do this step by step...
Thanks alot
