It means there's a race condition.  There are two drivers, one in X, one
in the kernel.  He's suggesting the kernel driver is taking so long to
load that the X driver is going ahead and loading without it.  When the
X driver does this, it does not enable kms support (since by definition
kms depends on the kernel driver).

My guess had been that maybe the presence of the vesafb driver (which is
a generic kernel video driver) was delaying loading of the radeon kernel
driver.  But your test indicates it is not so (or at least not
sufficient).

I'm afraid at this point I'm out of my depth, since it appears to be an
issue with how the kernel and low level plumbing are enabling the kernel
modules, not anything X is doing wrong.  Either X loading needs to be
delayed or the kernel module needs loaded faster.  Anyway, so I'm going
to punt this to the kernel team; please follow up with them.
