DRI was enabled both on 2.6.27 and 2.6.28.
Today I also checked another hardware, a laptop with Pentium M CPU, Intel
chipset ICH6, and ATI M22 [Mobility Radeon X300]. Similar behavior: while in X
with active DPMS screen off ("xset dpms force off") there are nearly 60
wakeups/s instead of 3 wakeups/s with DPMS disabled.
I've not done a git bisect before. It will take me a while.
