Hi Elroy, Simon, and Daniel,
Thanks for your responses. I've read similar things re: setting up RAID1 on an already-installed system being heinous and unbecoming. I'd read that Fedora supports fakeraid (at least the Nvidia flavour) so I decided to wipe it all and give that a try, to see if I can nut this out myself. The results were comical... RAID works perfectly (not the nvraid, but FC supports booting from software raid devices).
My experience with software RAID1 under Ubuntu was rather good. I did a RAID install with two IDE drives for the first time about two weeks ago which was surprisingly easy. And I've had a play with raid5 on three scsi drives. Also rebuilt a server last week.. two 200G SCSI drives, both partitioned as 198G raid and 2G swap, then configured the two raid partitions into one /dev/md0, then went back and set up /dev/md0 as ext3 root. Only one thing to watch out for, if the drives were already partitioned for RAID the installer gets horribly confused. Remove all previous partitions from all the drives and reboot so the installer kernel doesn't have any 'preconceptions' about how the drives are configured, and everything should be fairly straightforward after that.
