Did you try my preploader. It attempts to remap all the PCI resources to
something sane and even includes a black list for devices who lie about
their requirement (S3). For the latest version I've got success reports on
quite a lot of Motorola boards: 

	MVME230x, 2300SC, 2400, 260x, 2700, 3600, MTX and MPC750

and for now also 0 failure reports ;-). I'm expecting some however...
And I'm sure it will fail when somebody tries to use CompactPCI board with
an MPC750 since I've not yet implemented support for PCI<->PCI bridges
(I can't test it).
