I've been trying out an all-modular 2.1.73 kernel.
Building the IDE driver as module fails for a couple of reasons:
1) ide-probe.c uses the ideprobe_init routine before it is declared.

3) The ide.o and ide-proc.o modules depend on each other; you cannot load one before the other (catch-22). One solution is to link these together statically with "ld -r -o ide_mod.o ide.o ide-proc.o" and then install the ide_mod.o file instead of the two original modules. Is that how it should be done ? The thing loads and works, except that /proc/ide is empty.
