You may have a look at how we've solved this for MIPS, where we have a mixture of bus arrangements for different platforms, starting from pure ISA/EISA ones, ones with PCI and a PCI-(E)ISA bridge, legacy-free PCI ones and systems with no Intel-style buses at all, like TURBOchannel ones. See "asm-mips/mach-generic/ide.h" for a simple solution that fits all so far. I'm not sure whether the most recent version of the file has been merged upstream -- you may have to have look at: "http://www.linux-mips.org/cvsweb/linux/include/asm-mips/mach-generic/ide.h"; instead.
