Since nobody else responded...  :)

I threw caution to the wind and updated my firmware (turns out the 
machines were using 9550SX controllers, not 9500) from 3.04 to 3.08 on a 
couple of production CentOS 4 and my test CentOS 5 machines.  EXT3 
performance seems to have improved noticeably on the RAID 0 devices I 
tested so it might be worth the update.
