The I2C driver is in the -devel branch, but did not make it into the  
beta2. The MSP430 bus architecture is undergoing a bit of fine tuning  
right now to ensure that different bus protocols always follow the  
chip's requirements for bus reconfiguration. These changes seem to be  
going smoothly, so they should be making their way into the main  
branch pretty soon. Until then, you can checkout the -devel branch by  
passing this option to either update or checkout:

cvs update -r tinyos-2_0_devel-BRANCH
cvs checkout -r tinyos-2_0_devel-BRANCH
