Though the more I think about this the more I want to put this in ELFBios (which may sit in the LinuxBIOS tree) and not in the core. There are so many weird issues. Having the bootloader do the work may be the best thing. Especially when you get things vga initialization, and people wanting to do open firmware. The most interesting case I have personally seen is plugging a dolphin card into a high a machine with 6GB of ram. With the default dolphin settings you loose at least 1GB of ram... It wanted a 512MByte pci region. Eric
