I've got a server back for testing, I even don't manage to boot with  
2.6.16 or
2.6.17-rc5 (kernel panic just after kernel loading).

I'll try 2.6.14 or keep the well working 2.6.13.
Linux only see 7 GB of memory instead of 8, configuring Opteron with  
Linux
is pain.

For a good controller there is the LSI Megaraid
