The 54xx series has a different JTAG protocol than earlier versions. 
I have the same board and FET but I use it under windows with the Elprotronic programmer, so I don't know whether support for this new protocol has been built into the binutils yet.
I know that the version of msp430-jtag which I use (the last mspgcc3 build for windows) does not support the 54xx devices.

Yes, my 2008 mspgcc supports it too, yet this is the compiler, not the binutils.
For the compiler, only the linker scripts and the header files had to be built and the support for the MSP430X assembly commands had to be added to the assembler. This was possible right from the docs.
For the binutils,a real system is necessary for development, including anaylsis of the new JTAG protocol (which isn't documented by TI AFAIK).

Actually not.
The latest mails I read about this talked about using an alternative flashing tool (don't remember which). But maybe there was news I missed.
