Bug#498673: xserver-xorg-video-intel: 3D acceleration is very slow in absence of heavy load on the CPU
Hi, This problem do remain with Squeeze. 3D display is slow to similar extent as before.

Yes, the no. of interrupts for IRQ16 (Graphics) do increase in /proc/interrupts after running 'glxgears'.

Note that I do get the same behaviour of FPS while using `stellarium' in both the cases mentioned above. I thought of CPU frequency being lower is repsponsible. However, I checked that when `glxgears' is on, 1 of the CPU does change frequenecy (cpufreq_ondemand) from 1.998 to 3.0 GHz. Therefore, it appears that there it is not utilising the CPU power available with the present implementation of its DRI and I am filing a bug report in this regard. I am also attaching the output of 'lsmod' '/proc/cpuinfo' and 'lspci' at the end of this report. Note that I am running a 'kernel.org' unmodified 2.6.26.3, however, I found the same behaviour while using the Lenny 2.6.26-1 kernel.
