Thanks for the reply. It is a radeon 7500 chip. The problem is after the 
kernel reorg of the graphics section radeonfb gets built but does not 
get used. This is 'new' with 2.6.21 kernels. Are your running a 2.6.21 
or later kernel? If so does it use radeonfb? - Dan

If someone has a thinkpad with a radeon chip configured to support a low
power suspend can they forward a .config file?

Which kind of graphic chip does your thinkpad have?
