Thank you. I tried that. I added the following to grub:         
video=radeonfb:force_sleep

The Xorg log does not show this as an option. It and Radeon appear 
active and creating a log. However it does not show up as a module and 
normal means of passing parameters to it do not appear to work.

Thanks - Dan

How is radoenfb being managed? (It is included in initrd via 
/etc/sysconfig/initrd)
How can a load parameter be passed in this situation?

	Hello,

  To start radeonfb on my 2.6.22 Linux kernel, I give 'video=radeonfb'
on the kernel command line (in Grub...).

	Hope it helps...
