In my bunch of PCMCIA/Cardbus/PCI changes, I have one patch which decouples CONFIG_ISA from the PCMCIA subsystem, replacing it with CONFIG_PCMCIA_PROBE - on statically mapped PCMCIA systems (eg, SA1110) all the region probing, resource handling, and interrupt stuff is rather heavy weight. However, decoupling it from CONFIG_ISA would allow all that supporting code to remain when required for some socket drivers.
I'm working through getting stuff tested and in to Linus in a reasonable way. Of course, this won't help for 2.4 based kernels, although the CONFIG_PCMCIA_PROBE has existed in the ARM tree for a fair while and could, given someone with enough motivation, the relevant changes could be dug out and submitted to Marcello.
