My computer with a radeon is at home so I can't get to it right now.=20
Here's an example one from my website.  It's for the mergedfb support
I'm writing for savage chips, but it's identical to radeon/sis/etc.=20
Just change the driver line to "ati" or "radeon"

you may also need to add the Monitorlayout option if you are having
trouble with output detection.
