I am using a Matrox G450 AGP and a Voodoo 3 PCI card. The BIOS is set to 
detect the dual-head AGP card first. 

Here's what 8.2 set up during the initial install (configure all heads 
independently):

Section "Device"
    Identifier  "Voodoo Banshee (generic) 1"
    VendorName  "Unknown"
    BoardName   "Unknown"
    Driver      "tdfx"
#    VideoRam    32768
    # Clock lines


    # Uncomment following option if you see a big white block
    # instead of the cursor!
    #    Option      "sw_cursor"

    Option      "AGPMode"  "1"
    Option      "DPMS"  "on"
    BusID       "PCI:0:15:0"
EndSection

Here's lspci:

00:0f.0 VGA compatible controller: 3Dfx Interactive, Inc. Voodoo Banshee (rev 
03)
01:05.0 VGA compatible controller: Matrox Graphics, Inc. MGA G400 AGP (rev 82)

So the setup program is getting terribly confused. 

With runlevel 5, I get blank screens on :0.0 and :0.1 and a mess on :0.2.
