Thanks for the heads up. I did the swap while powered down and only brought the system up using an Ubuntu Live CD, so the udev on my current root partition didn't come into play. During that live-CD boot, I had no apparent problems with the changing device names. They had changed pretty significantly: sdb became sdd, sdc became sdb, sdd became sde, and another device not part of the array became sdc. In spite of the shuffle and a new SATA controller, mdadm was able to reassemble the RAID devices on those drive partitions with no input from me. I believe this is because mdadm scanned the partitions looking device for the appropriate UUIDs in the metadata, and with all the devices accounted for, it was able to "do the right thing". I was very impressed. When I boot using the original root partition (running Ubuntu Hardy), maybe udev will shuffle the device names more severely. But so long as mdadm is configured to scan all the available partitions, I expect it will locate all the pieces, whatever they may be named, and successfully reassemble the arrays.
