Here is a doc with caveat to all of this… and we have the 12S and so buying an X won't work.
* The 3750-X Fiber switches (WS-C3750X-12S and WS-C3750X-24S) don't stack with the old WS-C3750G-12S switches due to HW and SW limitations on the WS-C3750G-12S. © 2011 Cisco and/or its affiliates.

I have heard both Yes and No from Cisco ? http://www.cisco.com/en/US/prod/collateral/switches/ps5718/ps6406/data_sheet_c78-584733.html The answer is yes, but... you need to be careful to run the same version of software with a compatible license. In practice, this means that you will need to use at least the IP Base license on the -X switch. Also, you may need to check whether running multiple -x switches in a stack with other 3750s will disable stackpower completely.
