I'm with Linus 100% here.
It's really irritating to upgrade to a newer kernel,
using the same old .config file, and then discover that
my MythTV box no longer auto-boots to record programs.
The reason being, that /proc/acpi/alarm no longer exists,
and the kernel option to configure it has mysteriously
disappeared from the menus.
After an hour of hand examining and grep'ing Kconfig files,
I eventually find the secret little totally-unrelated option
that has to be selected to make the ACPI alarm option visible
again.
Doh!
That interface is driven entirely backwards.
The funtionality option should always be visible,
and should "select" (or hey, invent a better mechanism,
I'm not fussy), the underlying crap required to let me use it.
Cheers
