Well, I tried, and unfortunately I can not say that I'm happy after the 
upgrade. :(

Particularly, adapter now takes *VERY* long time (>10 minutes) to initialize, 
and report as "ERROR" in BIOS utility (while seeing all 24 disks; however, it 
reports 8 x36 expanders instead of one).

I can't boot the system off this array yet; will experiment further :(
