You need a newer kernel.

This is from OFfb and thus bogus.

Recent benh kernel or at least 2.4.18.

All cons, no pros really.
The 4.2.0 or later ati/radeon driver should work with Option "UseFBDev"
if you're running radeonfb. You'll have to provide a 1280x854 mode
definition (fbset -x). If you want DRI, you need to get the current DRI
CVS.
