[rescue] E250, U80, and RAM

[Joshua Boyd]

I see that some memory kits are compatible across a E250 and a U80.  I
also see that some kits don't seem to list both.  Is there anything is
really not compatible with either machine (meaning they just chose not
to qualify it), or are all sticks interchangable?  

In particular I want to move memory from a E250 to upgrade a U80 before
trying to find a new home for the E250.
