In case you decide to work on this yourself, this might be useful: 

Ideally, specifications like 

xyplot(depth ~ x, ylim = c(10, 0)) 

should reverse the y-axis direction. As pointed out some time back, this 
doesn't work in lattice currently, but that should be fixed in the future (it 
already works in my development version).

These should be easy to modify.
