In up mode, all output modes are useful for TACCR0
The MSP430x2xx Family User's Guide, the section on Timer_A output modes claims that "Output modes 2, 3, 6, and 7 are not useful for output unit 0, because EQUx = EQU0". However, the output example for up mode states "The OUTx signal is changed when the timer counts up to the TACCRx value, and rolls from TACCR0 to zero, depending on the output mode." Based on this, it seems those output modes are useful: they could create a one cycle pulse. This does actually work; I used it to drive the BLANK input of a TLC5940.
