Actually, it turns out that the obvious analog works with bwplot too
(though it's a bit weird that you can 'identify' points that are not
actually plotted). See below.

There's panel.identify(). You could use it as part of your panel
function, but in this case it might be more natural to do it after the
fact, as in:
bwplot(x)
trellis.focus("panel", 1, 1)
panel.identify()
trellis.unfocus()
This has the added advantage that you don't have to specify 'x' and 'y'
explicitly, they're taken from the corresponding panel data.
