It is possible to have a pair x4 slots like I want. Each of them being the proper dimensions of x4 so that the cards will fit (i.e. LSI) but only have two PCI-E lanes connected to each of the slots so that x4 lanes and cards fit but run at x2 speed. 500 mb/s @x2 would be plenty fast enough for a simple SCSI raid array(ultra 320 single channel) and dual channel controlers would requre more bandwith than x2.
