Yeah, let's delay it for the next merge window - it looks like it needs
more experimenting and since it is not urgent enough...
FWIW, I did play a bit with it today and I ended up with the diff below
just to satisfy the CONFIG_PCI/MSI deps. However, if I want to shut them
all up, I need to pull in SMP, MODULE_UNLOAD, MODULE... and so on.
Which is kind of an overkill and I really don't want to do it.
I wonder if one can exclude options from randconfig until 'select' has
been taught to resolve dependencies...
