It shouldn't (unless you have messed with lattice.options()). Can you 
provide an example? The following doesn't do anything unusual for me:

xyplot(1~1, 
       par.settings = 
       list(layout.heights = list(key.top = 100, key.bottom = 100)))

(I'm running r-devel though, so there's a small chance something might 
be different.)
