XFX Radeon HD 6850 Problems!

[jzhang18]

The same card here. I try to figure out why it does not work.
XFX 6850 ZNFC works OOB. 2 DVI ports work, HDMI also works

Inserting XFX 6850 ZCFC, Nothing works, neither of 2 DVI, nor 2 mini DisplayPorts.

The same company, what makes above 2 cards a huge difference to Apple Lion?
If someone has any suggestions, please give me a post
Really appreciated

These are all 6850 cards, supported by latest Chameleon, (ati.c source code)

619 { 0x6739,0xAA881002, CHIP_FAMILY_BARTS,"AMD Radeon HD 6850",kDuckweed},
620 { 0x6739,0x03B41043, CHIP_FAMILY_BARTS,"AMD Radeon HD 6850",kDuckweed},
621 { 0x6739,0x21F81458, CHIP_FAMILY_BARTS,"AMD Radeon HD 6850",kBulrushes},
622 { 0x6739,0x24411462, CHIP_FAMILY_BARTS,"AMD Radeon HD 6850",kDuckweed},
623 { 0x6739,0x31101682, CHIP_FAMILY_BARTS,"AMD Radeon HD 6850",kDuckweed},
624 { 0x6739,0x67391002, CHIP_FAMILY_BARTS,"AMD Radeon HD 6850",kDuckweed},
625 { 0x6739,0xE177174B, CHIP_FAMILY_BARTS,"AMD Radeon HD 6850",kDuckweed},

XFX 6850 ZNFC is inside :623 { 0x6739,0x31101682, ...}
XFX 6850 ZCFC is not, it should be something like ---
NNN { 0x6739,0x31171682, CHIP_FAMILY_BARTS,"AMD Radeon HD 6850",kDuckweed},

Hope it will be added and supported in near future.
