Yes, with 

xyplot(conc ~ uptake | Treatment + Type, data = CO2,
       scales = list(x = list(log = TRUE)))

No, but that isn't always the most appropriate thing anyway (the ticks 
may get too close). You can always specify the locations manually, as 
in

xyplot(conc ~ uptake | Treatment + Type, data = CO2,
       scales =
       list(x =
            list(log = TRUE,
                 at = c(10, 20, 30, 40))))

Ideally, the tick locations should be computed by (a variation of) 
'axTicks', but I've never gotten around to implementing that.
