Thanks for that - that has got me a lot further now.
The only issue was the IDT audio however didn't work but I guess it's all from a different laptop so there was always likely to be some discordance. The system string is HDAUDIO\FUNC_01&VEN_111D&DEV_76E5&SUBSYS_103C193B&REV_1003. That said the sound seems to be working fine out of box albeit a bit crackly.
I then managed to the video card sorted by using the AMD beta drivers (the standard one claims to not find a compatible video card).

So far I've got the wireless, ethernet, usb 3.0 and video card working. I'm not sure how the touchscreen is supposed to work under windows 7 - it seems to be doing ok as far as I can see.
