The current release of Trellis doesn't support log scale.
The next release of Trellis will give user much more control
over the panel axes; in addition to log axes, user will also be able to
supply custom tick labels, etc. (pretty much all the control you would
have in axis() ...).  This will be done through the specification
of a "scale" argument, for example:

	xyplot( ...., scale = list(x = list(
					relation = "free",
					log = 10,
					cex = .6),
				   y = list(
					labels = c("B", "G", "H"))))

This implies a free-scale log x-axis, and a customed labelled y-axis
for each panel. Notice you can pass graphical parameters down as well!
