At the risk of re-opening what appears to be a solved problem: In that case, mspgcc should have built a binary for the default processor (msp430f110), which would have put the text at 0xfc00 and the interrupt vector at 0xffe0. (Confirm that with readelf -e and look for the .text and .vectors sections.)
If mspdebug wrote the text section to 0x8000 and the vectors to 0xffc0 anyway, it must have selected addresses based on the chip being programmed, rather than what was specified in the object file. Daniel, can you confirm this is how mspdebug works? If it's true, it seems to have the potential for biting people who try to do tricky things like use non-standard memory layouts. Or maybe not. Good to know that it could happen, though.
