I've been using one (early 2008 model?) for several weeks now. Suspend works, hw.setperf works, radeondrm works for X, internal audio doesn't seem to work, but I can't say I've spent a long time trying to make it work.
There are a few minor issues, like the console framebuffer doesn't take up the whole screen [1] (although it does expand to more than 80x24), and sometimes in the consoles, all keyboard entry is garbled, and an (obviously incorrect, although possibly what it would be if I held alt) keypress is registered on both keyup and kendown, which makes it impossible to login or even switch back to X. [2] But overall, it's pretty nice. It builds the kernel from scratch in just over 5 minutes, and hardware support is good enough for what I need.
