E.g. there is only a entry for CARD_AMD_RADEON_HD7800 which has a pci id of 0x6819 which is the 7850. The 7870, on the other hand, has a pci id of 0x6818.
No, it doesn't work like that. You can't distinguish a 7850 from a 7870 based on the PCI ID. Note that even if you could that wouldn't help though, since e.g. fglrx will report both as "AMD Radeon HD 7800 Series".
Is this true for Volcanic Islands as well? The R7/R9 cards do need to be added as well, but they aren't listed on AMD's site in the generic form. I guess they need someone who owns one of those cards to check it.
