I have the same setup, but with 2 DisplayPort monitors and 2 DVI monitors via
DP->DVI adapters.  This is currently working only with the nvidia driver under
Fedora 13:

<NVS420>[VHDCI]-+---[DP1][DP3]
                |
                +---[DP2][DP4]
                      |    |
                  [DVI2]  [DVI4]

I also needed to supply EDID dump files of the two DVI monitors directly to the
X server in order for them to work correctly, even with the nvidia driver:

Section "Screen"
  Option         "CustomEDID" "DFP-0:/etc/X11/2001fp-edid.bin;
DFP-1:/etc/X11/2001fp-edid.bin"

DP2/DVI2 shows up as DFP-0 at PCI:4:0:0 (GPU-0)
DP4/DVI4 shows up as DFP-1 at PCI:4:0:0 (GPU-0)
DP1 shows up as DFP-2 at PCI:3:0:0 (GPU-1)
DP3 shows up as DFP-3 at PCI:3:0:0 (GPU-1)

I have a serial console hooked up in order to be able to perform any necessary
debugging.
