Now tested with following hwpack and rootfs:
http://snapshots.linaro.org/precise/hwpacks/lt-panda-x11-base/305/hwpack_linaro-lt-panda-x11-base_20120912-305_armhf_supported.tar.gz
http://snapshots.linaro.org/precise/images/ubuntu-desktop/412/linaro-precise-ubuntu-desktop-20120912-412.tar.gz

I tested textures demo and added one debugging log to
http://pastebin.com/9VjcHzmt

I think this backtrace is the most relevant part of the log:
