I understand that there is numerous resentment against having this file
in the kernel and I've been thinking of a solution without it. One such
path would be serving the kernel with a OCP list of the devices used,
but I'm unsure about the current status of OCP. Is this The Right Way to
do it, or are OCP likely to be abandoned further along the 2.6 road?

If you are talking about 2.6, dont use OCP.  Use the driver model and platform devices.  You can take a look at the arch/ppc/syslib/ppc_sys.c and arch/ppc/platforms/85xx for examples.
