I don't want to defend ATI here or anything, but I use the 64-bit fglrx 
8.19.10 with 2.6.15-rc5 and it works (except for the minor patch for 
2.6.15-rc2-git3 and later that we came out with with Hugh Dickins and that 
was sent to the list not long ago).

The problem with PCIe is, that IMHO they do not activate the acceleration 
unless an AGP is detected (at least that's what it sounds to me like). If 
there is PCIe, there is no AGP, though AGP is not detected, and 
acceleration is not enabled. I think it may be as simple as that. I was 
reporting this to ATI a while ago. I haven't tried the new fglrx 8.20.8 
yet, but if they read the reports at all, then there's a good chance that 
this may be fixed there already.
