Both show steadily increasing biovec-1. uglybox was previously running Ingo's 2.6.11-rc2-RT-V0.7.36-03, and was well over 3,000,000 bios after about a week of uptime. With only 512M of memory, it was pretty sluggish. Interesting that the 4-disk RAID5 seems to be growing about 4 times as fast as the RAID1. If there's anything else that could help, or patches you want me to try, just ask.
