All raidframe support is built-in on my kernel (includes GENERIC and
elides unnecessary/unwanted items). If I disable all the raid* stuff,
won't that disable raidframe as well?
It's important that everything raidframe/raid related be disabled before
the kernel boots, or my RAID will be hosed again and I don't need that
level of stress. I was lucky to recover it the first time (have
encountered a few damaged files since then).

I think that means if I disable something via userconf, the on-disk
loadable module won't be loaded.

I suppose I could whip up a custom kernel without the raidframe/raid
support in it, but it's crucial to keep the raidframe module from being
loaded if any disk is found with RAID autoconf support.
I suppose also I can turn off autoconfig on the RAID before booting the
test kernel (the config file is renamed so it won't be found by the
I have another machine with a local raidframe raid that I can test the
procedure with when current tasks are completed.
