IIRC, the 2650 uses the aacraid controller.  You don't get to the
Megaraids until you hit the 2850/2950 series.  We use 1850s, 1950s,
2850s and 2950s a lot--I'm not sure about the 2650.  The fact that the
aacraid driver was loaded indicates to me that THAT's the controller
you have.

I did a quick survey of our stuff.  The 18xx/19xx machines use the
aacraid as well.  We don't see Megaraids until we hit the 28xx/29xx
units.
