[R] CI for Ratios of Variance components in lme?

My apologies if this is obvious:

Is there a simple way (other than simulation or bootstrapping) to obtain a (approximate)confidence interval for the ratio of 2 variance components in a fitted lme model? -- In particular, if there are only 2 components (1 grouping factor). I'm using nlme but lme4 would be fine, too.
