I tracked down the source of my problem and it is nothing to to with 
the RadeonHD driver. By mentioning this here I hope it will be of use 
to people suffering the same symptoms.

I'm afraid it was a mistake on my part. Remember when I said to ignore 
the fact that the log said "FreeBSD 7.0" and that as far as I knew I 
was running 7.2. Turns out I don't know far enough.

I am running ZFS, which the FreeBSD boot loader doesn't understand 
yet. Therefore you need a small boot stub to launch the proper system. 
It is from this boot stub that the kernel is loaded. Unfortunately 
when you install a new kernel it does not install to that stub.

It installs to /boot/kernel on the ZFS disc and to /bootdir/kernel, 
which is where the stub is mounted. It should be installing to 
/bootdir/boot/kernel.

Once I copied the kernel to /bootdir/boot/kernel it all came good. I 
am now able to use the radeonhd driver with X and a number of annoying 
boot time error messages have gone away into the bargain.
