The libdrm tarball doesn't contain the kernel modules. That README is
more for the intention of checking out the drm git repository, which
has both the library and kernel modules. It may be too late now, but
you might not want to replace your system libdrm. You can easily stuff
it in /usr/local or /opt or $HOME.

If you follow the intel guide, you should install a newer kernel which
has the updated drm modules.

The important thing is the pkgconfig file. You need to update the
PKG_CONFIG_PATH environment variable to point to the directory where
your freshly installed libdrm.pc is installed. Intel has a guide for
building, but it has some misinformation. You might want to see the
Xorg wiki, which is more in depth. Here's both pages.

http://wiki.x.org/wiki/Development/git

The bit about building lidbrm as --prefix=/usr --exec-prefix=/ is not
correct. This will put the libraries and pkgconfig file in /lib and
/lib/pkgconfig. pkg-config does not look there by default, only
/usr/lib/pkgconfig. But, again, it would probably be better to just
install the components outside of the system directories.
