On a fresh install today from the precise desktop cd I tried to turn on KMS with radeon.modeset=1. This brought me to a running in low graphics mode message.
It is because of a race issue described in the KMS wiki https://wiki.ubuntu.com/X/KernelModeSetting . I have the "RADEONDRIGetVersion failed" message in the Xorg.0.log. It used to be the case that you would end up at a terminal becuase of this.
This is why I am requesting KMS on by default for radeon cards. On kernels where KMS is on (lucid, debian sid) you don't have this problem.
