By "Drm itself" I assume you are referring to libdrm.

IIRC it is just waiting for browsers to add cacert.org to trusted root
certificates, it should be fine to accept.

These look funny. Did you build your kernel from the same source tree
the DRM is using (/lib/modules/2.6.26/source)?
I haven't seen these errors before, but my first guess would be an
unconfigured or never-compiled kernel source tree. Hmm, yes, at least
include/linux/bounds.h is a build-time generated file.

If you are using a precompiled kernel image from your favourite
distribution, you might need to install also another package which allows
building custom kernel modules. This is distro specific.
