Hmmm... if I realised that I wouldn't have been so hung up about getting a 
board with RAID support in amd/64!  (Although I do like the Asus A8V Deluxes 
now I've got one.)  I assumed on-board RAID was a step up from geom but maybe 
not.  I guess performance in geom wouldn't be any slower either if it's all
