FWIW, I believe only the ia32 kernels have 4KSTACKS turned on... last I 
checked Opteron still did not have this option... feel free to correct 
me if I'm wrong.

xfs over normal ide/scsi should be fine w/ 4kstacks; if you start piling 
lvm on top of md under nfs etc etc, you could start running into stack 
issues with 4KSTACKS.
