Hm... I also use a radeon (w/ KMS) and needs this binary blob but I
compile that into the kernel*.
*Device Drivers --->
Generic Driver Options --->
[*] Include in-kernel firmware blobs in kernel binary
If you don't have it compiled in I can see why you would need udev...
Disclaimer: I assume it's not needed in my case - haven't tested though
but fail to see any technical reason for calling libudev, in this case.
Also, this work around... I'm not so sure it's a good solution to
require a pseudo need for udev which is placed on / before mounting /usr
but then again we (can) have a static /dev before {u,m}dev takes over...
