Been many threads discussing this issue already, and yes, it will work IF you put another thunderbolt device inbetween the display and your other monitor. If you just plug a regular display into the thunderbolt display you won't get a picture (for somewhat complicated technical reasons.)
Needless to say, this other thunderbolt display also needs to have a daisy-chain port, or you'll be caught with your b...eard in a wringer.
