changing LVDS contrast level on Thinkpad with M22 [Mobility Radeon X300] -- is it possible?

I am using an IBM Thinkpad T43 2668-6ZU. My goal is to change the
contrast setting on the LVDS panel, which is not possible with any of
the IBM hotkeys, etc. I have checked the default proprietary ATI
utilities that come with the Microsoft Windows XP drivers, and they have
a setting for LVDS contrast between "0" and "200". I note that the
proprietary ATI fglrx driver *is not* able to change this contrast
setting.
I want to be clear here that I am not talking about the XVideo contrast
changing which can be done with xvattr -- that works with applications
that use the XVideo extensions, but only changes the video itself.
The LVDS itself has a native contrast setting that I only discovered
myself recently when switching to a laptop that had a native setting
that was extremely high contrast and difficult to use. Of course, with
a standard monitor, you can just adjust it with standard settings, but
IBM Thinkpads have only brightness and no contrast settings.
I have tried both ddccontrol and radeontool to attempt to change this.
Below are the results from ddccontrol attempts, and the output of
registers given by radeontool. I simply don't know enough to figure out
what register I should try to change for this setting, and I would
appreciate any suggestions that anyone has. I read the source of both
ddccontrol, the radeonfb Linux driver, and the radeon xorg driver, but I
simply don't know enough about low level video card programming to be
useful in this regard, but would be happy to help figure it out by
trying things on this hardware.
Thanks!
# modprobe i2c-dev && modprobe radeonfb && ddccontrol -p -v

I am using Linux 2.6.24-23-generic #1 SMP Thu Nov 27 18:44:42 UTC 2008
i686 as shipped with Ubuntu hardy.
Interestingly, some information is returned about the video via
i2cdetect:
# i2cdetect -l
i2c-0 i2c monid I2C adapter
i2c-1 i2c dvi I2C adapter
i2c-2 i2c vga I2C adapter
i2c-3 i2c crt2 I2C adapter
However, I have tried various i2cdump commands, and it returns only
XX's; I don't know what that means.
Here's some data from /proc that might be of interest:
