Not quite the same thing, but I sent this a while ago:

http://lkml.indiana.edu/hypermail/linux/kernel/1304.3/02847.html

My "softdepends" feature is probably not needed, as pointed out in the
thread, as the behavior can be implemented with the current Kconfig
language just fine.

I had a quick look at fbdev drivers, and some of them compile fine on
all (well, arm and x86) archs. But many do have real arch dependencies.

I think it'd be a good long term goal to make drivers arch-independent,
and add CONFIG_SHOW_ALL_DRIVERS or such, which would allow compiling
drivers that are not used on your arch, but still compile fine.
