You could try using the radeontool (google it) to remedy this.

Wow, you mean to say that you can flawlessly S3 suspend/resume with
kernel 2.4?  I would assume that this is due to your laptop's support
for S3 in BIOS.  Not all laptops have this... see for instance what Ole
had to do to get his working:
http://home.cern.ch/mrohne/P2120/P2120_Linux_S3.html

Drivers in the new kernel need to be able to suspend/resume (S1, S3 and
S4) without more than the minimum required support in the BIOS.

Thanks,
Charl
