They should be already aware that most ISA drivers are just 
not maintained anymore and very likely broken. I doubt there is any bug 
hunter or maintainer who is not aware of this fact.

There are no x86-64 machines with ISA slots. I think it is very related
to ISA to disable drivers that are not used since the hardware has 
no physical mean to support it (yes, I am aware of PCMCIA, but that
is not included in CONFIG_ISA). Same reason to not support
CONFIG_EISA. LPC devices in southbridges are a different thing, but
there doesn't seem to be any reason right now to add a CONFIG_LPC.
If there was one I would have no problems with setting it.

Anyways, this is only tangential to the original reason for the patch.
Can you please drop the bogus ISA dependencies. Jean has clearly stated
that the drivers have nothing to do with ISA itself.

Here's the patch again for your convenience.
