st: Using time invariant variable as instrument in fixed effects?

Dear Statalist,
Is it possible for me to use a time invariant variable as an instrument in a
fixed effects regression?  I am currently using xtivreg, and it is demeaning
the instrument I want to use and causing the endogenous variable to drop out
of the regression.
Thanks,
Lisa
