I also has a new Vostro 3400 that comes with the the new nvidia hybrid graphic video card (nVidia GT310n w Intel GMA). The Vostro BIOS doesn't have the feature to just disable the Hybrid Grahphic Card, so we have to live with both of them.
On my computer, it also seems like the bootloader is being "confused" by seeing the Intel GMA.
Here is the part of the error code when I start with -v (Chameleon-2.0-RC5-r416)
Using PCI-Root-UID value: 0
nVidia Unknown 1MB NViff [10de:0a75] :: PciRoot(0x0)/Pci(0x1,0x0)/Pci(0x0,0x0)
ERROR: nVidia ROM Patching Failed!
Intel VGA Controller [8086:0046] :: PciRoot(0x0)/Pci(0x2,0x0) (currently NOT SUPPORTED)
Thank you.
