Anyone else have a Radeon 2600 Replacement card Infant Failure?
Follow-up to his original report on Feb 23rd regarding Apple's Exchange/Refund Program for certain S/N Radeon 2600 XT's w/Distorted Video. (Added to his original post there also.)

"Just a follow up on this. The first replacement card, installed by the Apple Store 5th Ave, failed after two days.
(I asked about this infant failure - i.e. total failure (no video) or distorted video?-Mike)
It was a total failure: after the second day of use, I put the machine to sleep using the Apple Menu-->Sleep command. The next day I could wake the machine (and successfully run a screenshare session into it), but the display never woke again (black display).
I then pleaded with Apple to send a technician to me, who replaced the card.
This second new card is still working, but as you can imagine I don't feel completely confident now about it.
Both these replacement cards had serial numbers within the affected range. I wrote to Apple about my concern but got no reply. Or, no reply at least until I read the (apple) document on the 2600 (program), which says "Apple will continue to evaluate the repair data and will provide further repair extensions if needed."
I am glad to hear it!
-Michael W."

I asked Michael to send a note if he saw any other failures of a replacement card. (Ditto for any other reader that has gotten a replacement 2600.) Hopefully just a random/infant failure but getting replacement cards in the affected S/N (suffix) listing in the apple doc understandably isn't confidence inspiring.

Radeon 6870 working w/OS X 10.6.6 Drivers from 2011 MBP?
I don't have a 6870 card to test/prove this, but here's a clip from a post at

"According to The Rominator, radeon 6870 works fine in snowleopard (and in MacPro too, just no boot screen), if you use ati drivers from 10.6.6 mbp dvd (ati6000controller.kext atisupport.kext atiframebuffer.kext).
All 4 ports work, even DP, no need for injector."

The netkas post includes an ASP screenshot.
(A reply to the post also said Reference (PC) 5870's worked using the ATI kexts from a 2011 MBP w/o needing an injector or enabler.)
See later posts/comments at the linked page. (And also a later follow-up post -
The 6870 is a lower-power (and slightly lower performance) version of the 5870.
