Damn, you have a valid point too. I need to think about it...

... well, the only thing I can think of right now is to remove the
dependency on BLK_DEV_INITRD completely - I believe this is what you
proposed initially Markus - and add a BIG FAT SUGGESTION to Kconfig
saying that people should strive for enabling early microcode loading if
possible.

This is the only way I see we can handle "make oldconfig" without
BLK_DEV_INITRD and microcode built-in into the kernel cases relatively
fair.

Hmmm.

Or I could hack "oldconfig" to issue that warning... Lemme think about
it and see how much Michal would scream at me for it. :-)
