Bug Description
11.10 64-bit alternate installer does not detect any disks/partitions when I get to the step after it asks me if I "want to activate the SATA RAID devices". After replying yes, no disks and/or partitions show up.
11.04 64-bit alternate installer works fine.
The 11.10 64-bit LiveCD also works fine but I need the alternate installer for an encrypted installation.
The problem seems to also be described here:

If this source is correct, apparently the mirroring (ie: RAID1) drivers aren't loaded in the 11.10 kernel. But then why were they loaded in 11.04? Was it purposefully or inadvertently left out?
I'd love to test RAID0 to see if that works but can't wipe this system and don't have another on hand.
