I need to correct something I wrote earlier.  The card has NO DisplayPort
adapter, but something proprietary (?), which splits into a pair of connectors
each having two DVI ports (4 DVI in total).  Apparently, the driver only thinks
it is a DisplayPort.  Here's a crude drawing:

<NVS420>[PORT]-+---[DVI1][DVI3]
               |
               +---[DVI2][DVI4]

DVI1 and 3 are at PCI:5:0:0 , DVI2, DVI4 at PCI:6:0:0.  The primary display is
attached to DVI1, second at DVI2.
