O.k. After adding the code to properly initialize the i8259 interrupt
controller, and the RTC, linux Boots!
On the alpha with 2.4.0 I don't even need to touch the PCI bus.
The only detail still waiting is how to enable writing to the flash
chip over the TIG bus.
For reference I have not needed to pull the 2MB AMD flash rom from
my system, despite the fact I made certain it was possible.
