UK Keyboard layout, driver ?

I know I'm missing something obvious, but....

I've a Thinkpad T40 and had to do a rebuild from the image on the hard drive. This left the " character on the @ key and vice versa, and the ₤, which should be on Shift 3, is of course a hash.

I've Googled my head off, checked the Lenovo support pages etc, but I still can't find a UK layout keyboard driver.

Anybody willing to help overcome this pathetic issue?

Thanks
