Install xp on sony vaio

Hello,
I have a Sony vaio VPC C series 64 bit laptop. I've a 2.5" IDE drive from my old laptop which has Windows Tablette OS - a version of XP.

I will image Win 7 on my Sony to a cd; but how can I then clone my old XP on the ide drive to the Sony hdd?

I know I need to d/l drivers for xp for the Sony, but was told I need to sysprep it 1st.
Is this true? Will I then be able to just clone the ide drive across, or do I need to set up a slipstream install with Bart?

Thanks
