Like Harold, I have also used simulation-based methods for power analyses, which 
I discuss (briefly) in the following article (with R code in an appendix):

Atkins, D. C. (2005).  Using multilevel models to analyze marital and family 
treatment data: Basic and advanced issues.  Journal of Family Psychology, 19, 

However, depending on the nature of your design, it could be far easier to use

Is there any way to compute power analysis for a mixed model ?
