Carl,
There is a procedure in Rosner [Rosner, B. "Fundamentals of Biostatistics, (6th ed.), Duxbury, Press (The Thompson Company): Belmont, CA, 2006, pgs. 199-201.]
If you send me your email, I can pass along a "not-ready-for-prime-time" .ado that I use for the calculation.

Subject: st: Fw: Calculating a confidence interval for population variance based upon sample.
Hi
I have STATA10.
I can not figure out how to calculate a simple confidence interval for a
population variance
based upon sample data. STATA will calculate the sample standard deviation,
but I can not figure out how to compute a confidence interval for the
population standard deviation. Is there a command which will do this?
Any help?
Thanx,
Carl
