i2c for Alpha

[phil@edgedesign.us (Philip Edelbrock)]

The I2C controller usually lives on the south bridge (the chip which has 
the slower I/O, like IDE, ISA, etc.).

Usually there are people maintaining kernels used for 'unusual' 
architectures (like PPC), you might see if there is someone who is 
patching and maintaining a stable 64-bit Alpha kernel for your 
application.  They'd be a good place to ask more general questions.  
Here's a good canidate I found with a quick Google search:
