remapping PC keyboards to work happily on a mac...

i've not had a chance to fully vet this process but will hopefully soon. At work I have a daskeyboard that I love very much, but there is no function key for things like forward delete(FN+backspace), and some of the function key mappings.
Here are a few pages I found on re-mapping keyboard keys on a mac.
