  Following given tips, I was able to reduce power drain during s2ram
of my Thinkpad X31. To do it, I had to :
- load the radeonfb module : it was a bit difficult because standard
Debian kernels I use have VESA framebuffer inside the kernel (not a
module) : I had to put radeonfb module in the initrd (giving its name
in /etc/initramfs/modules and re-building it with update-initramfs -u),
and I had to remove the 'vga=791' boot option in video=radeonfb .

- I had also to disable DRI from my Xorg config file : only using
radeonfb module wasn't sufficient. It helps also with powertop (the tip
was given on its list indeed).

	Thanks for your help,
		Fred.
