I'd look at the Highpoint drivers.
I've been using raid5 with samba-3_0 svn for a couple months now without 
incident.
On the other hand, I only use one additional IDE card, with one drive 
per channel which means 4 drives.  Nothing fancy, just a SIIG ATA.  
Didn't look to me like multiple ide cards were well supported.

Other than that, I'm running the same level raidtools, old Redhat 9 with 
2.4.20-28.9smp.
