Hmm.. I believe that an error may have been made in the cooking process of the rom you are using.. DCD is an awesome developer, but he doesn't develop for our device specifically.. I would recommend trying to use rstoyguy's or dogguy's kitchen and recooking your custom rom.. I know this may not be what you wanted to hear, but the only other recommendation is to send a PM to DCD for some advice. Good Luck, I know you have been looking hard for a solution.
**EDIT - I believe you are correct in that the radio version should not affect the SMS/TXT/MMS functionality regardless of carrier.
Check out these kitchens made specifically for the Vogue:
