I'm not sure, but I suspect it may have something to do with the 
device-mapper.  I know that's what I use for a striped array -- and yes, 
I have to make an initscript -- initrd, because I boot off the thing -- 
to set them up.  The good news is, the detection can be done in userland 
now -- since mine is nvidia raid, I can use dmraid, which runs entirely 
in userland, autodetects from BIOS settings, then sets up a proper 
device-mapper table in the kernel.

Device-mapper doesn't support everything yet (as far as I know), but the 
principle should be about the same for more complex RAID -- some 
userland tool.  There really is no reason for this autodetection to be 
in the kernel.

In the meantime, there may be rough edges...
