I doubt it's anything new in 2.6.15.2.

That's #2 so there should have been an earlier one, but never mind...

ATI's fglrx is Tainting your kernel.

I don't know 2.6.15.2_DL6, but never mind...

And further down...

Yes, fglrx definitely looks implicated. ATI were carefully coding around an anomaly in our page count handling, then 2.6.15 removed that anomaly, so their wrapper code needs an additional #ifdef on Linux kernel version. I'll forward you offline what Martin Drab posted a few weeks back.
