Interestingly we have a second machine here which has never had hardware RAID installed on it. The machine was always constructed with software RAID partitions yet the FC5 installer can't find these software RAID-1 partitions. Fortunately, we discovered that by passing the installer 'nodmraid' the md partition with the FC4 root linux installation becomes visible to the installer. Is anyone else finding that they have to disable dmraid to have their old software raid partitions found by the FC5 installer (specifically on machines which have never seen hardware RAID partitioning on their drives)?
