Since I am hip deep in debugging the PCI system.

In the .dts files there is the section for the PCI setup.

The interrupt-map = < >

Does this need to include:
1) A mapping for every IDSEL line in the system?
2) Only those IDSELs that are used on the slots on the motherboard?

I'm not sure I follow the difference between 1/2. The map needs to  
cover every IDSEL that has an IRQ line wired to it.

3) A custom entry for every card we want to support?

See above.

4) How does a bridge chip and slave busses affect the entries, if  
at all?

Uugh, I'm not sure how bridges are handled at this point.

Looking at the mpc8360 / 8349 setups that are part of the latest  
kernel
trees, some are place many and some are placing just a single entry?

Which should be the preferred method?

It depends on your HW setup, the 8360/49 boards have some 'odd' IDSEL  
irq mapping.
