Ikea website solution - depends on your country

Hi guys, I'm in Scotland and have just bought the Pax bedroom range including some carcasses that double up as either chest of drawers or wall mounted overbed cupboards - same problem - how on earth do you hang onto plasterboard. (And our wall is a double thickness plasterboard - its the dividing wall between our neighbours!) Ikea website and customer care is less than helpful!
However, thanks to Google, I have found the solution on the Ikea Canada website - click on the link above. Presumably an Ikea wall cupboard in kitchen is hung the same way as in the bedroom?
Now, next challenge - translate "suspension rail" into Ikea-speak and find out if they stock it in the UK?
PS Seems like IKEA cannot agree themselves - depends on which country you live in is seems:
For the UK, USA, Australia, there is a different suggested method - click here http://www.ikea.com/ms/en_GB/complet...llation_1.html
