Did you ever get a response to this? Assuming 3 of the 4 drives are still good, you should be in good shape. Just plug the drives into a spare box (Intel or AMD, 32 or 64 bit, it doesn't matter) and boot with an Ubuntu CD. The system should auto-detect both the RAID and LVM. You should be able to copy all of your files to a removable hard drive. Linux's software RAID is a real win in this situation, BTW. Hardware RAID cards are helpful when disks fail, but they're troublesome when it's the motherboard that fails instead.
