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: http://www.alphalinux.org/ Phil Jeff Sacksteder wrote: >>Most (all?) of the code is CPU independant.
