D40 and legacy / film Nikkor lenses ??

[expatCanuck]

Greetings -
Am looking to buy a Digital SLR.
I've got some older Nikkor single focal length lenses (used with my old Nikon FE), as well as some bigger (i.e. - heavy) Auto-Focus zooms on my N90.

As a rule, will the older lenses work with a D40?
Any caveats / gotcha's?

Thanks

- Richard
