Yes it is possible to have multiple cards with the same ID. For example, the 5770 and some 6770's share the same ID of 0x68B8, the only way to differentiate them is by the subsys_id.

In reviewing http://developer.amd.com/gpu_assets/ATI_Device_ID_List_July_2011.txt this looks like an error.

ok.so in the trunk effectively i see a new entry 6490m but are you sure it fit RV chipset? i tried to boot with this untouched trunk and to compile also a variant..but none are good in lion with graphicsenabler= yes i see always unsupported card! the secondary problem is the ability to catch data from the bus. i tried to use radeonpci and radrondump. (1st those tools run only in 32bit but the dump return the bios of the hd3000!! even if lion detect and load ati kects and framebuffer, there is no way to force switching. also ioreg reports.a lot of data.

Comment 7 by Cosmosis Jones, Oct 18, 2011
neermind i see you're using ATY_Init. I need a bdmesg and ioreg from you using GraphicsEnabler=YES as well. Thanks

ok sorry I can write only at this time everyday so I had atyinit for a test.. because if I use or not ATYinit I have the same output -> no info about any part of ATI display Because of dualgpu.. everywhere is wrotten to use pcirootid=1 and GraophicsEnabler=No.. So I attach the reports in GE Enabled yes and in GE Enabled NO. BUT with yes ort no I have the same.-> no ati believeme.. my philosophy is to leave as untouched as possible the S/L/E.. and my HPDV6 (recent HW sandybridge i7) and others similar are able to start with less patches. Then.. SATA/USB/CAM/PWRB/SLEEP are Ootb (sleep only if I patch dsdt/speedstep appleintelcpupowermanagement) remains:audio-video video is HD3000 (I see it fine in mac, always in the 16 combinations of :GEnabler:PCIrootid:Drivers:VBIOS) and the utility igfxxxx detects it fine. the only problem is that with ATI.C at boot (modded or last trunk) report : unsupported video card as I told above bye ugo

ah this is not just an ati.c issue.. This is the entire graphics enabler when u have more than 1 card. Just like when people have 2 nvdias, or 1 ati and 1 nvidia, they have to do an EFI string or a DSDT patch for the graphics.. We'll still keep this open..

k i see even if i consider it true/untrue i mean: in windows.the ati catalyst driver has a newer and fundamental option: the power management: you can force using ati instead of intel hd3000 that mean..i suppose..that ati can drive bith nd this is universal in all newer laptops..also apple but to complete the picture, there are models with thunderbolt engine..models with 6gb pcie and an external slot (ex an express card) and thosecheaper without any graphic expansion my opinion is that there are no 2 vga..but 2 engines switchables and it confirms the ioreg bye

CHIP_FAMILY_RV730 for 6490M and 6470M was changed to CHIP_FAMILY_CAICOS in revision 1657.
