Framerate drops after installing libdrm-intel1 / libdrm2 2.4.23

Hi Debian X Team

I noticed a frame rate drop of 50% percent after upgrading from
2.4.21 to 2.4.23 of libdrm-intel1 and libdrm2.

Before the install I ran glxgears which gave me constant FPS of ~1100.
After the upgrade it dropped to ~550.

Okay, I know that glxgears isn't much of a figure, but anyway this
is a huge number of frame drops.

My machine is a Auss UL30VT with an Intel GFX card:
00:02.0 VGA compatible controller: Intel Corporation Mobile 4 Series 
Chipset Integrated Graphics Controller (rev 07)
running an Debian unstable with X.Org X Server 1.7.7.


Best regards
