Here is the paths I collected for distros I'm interested, you could see how difference they are
* Ubuntu/Debain bit: /usr/lib/x86_64-linux-gnu/dri/i965_drv_video.so
* Ubuntu/Debain bit: /usr/lib/i386-linux-gnu/dri/i965_drv_video.so
* Tizen(32bit):  /usr/lib/dri/i965_dri.so
* Fedora/Mandriva 64: /usr/lib64/va/drivers/i965_drv_video.so
* Fedora/Mandriva 32: /usr/lib/va/drivers/i965_drv_video.so (guessing)
