R help - Aug 2005 - simplifying a lmer model

I have been using lmer in lme4() to analyse the effect of dropping a term from 
the model as below 
anova.name<-anova(m1,m2)
Where m1 is an original model and m2 has one term removed. I can then create 
my own type III tables for each variable in the model. However with many 
variables this becomes exceedingly time consuming! 
anova.lme in nlme() and Anova() in car dont seem to work for lme objects 
created with lmer? Is there any other way to create type III tables?
Any help much appreciated.

I haven't played nearly as much with lme4 as I perhaps should have,
but my first try would be to see whether drop1 works on lmer models.
