There is a need to not only put the video device to a lower power mode,
but to restore the different states of the video card, so I think no.

There is a support available using the radeon frame buffer but
for powerpc achitecture.  This was written by ATI people.

Some people reported this worked for their i386 based
laptops after hacking a little the radeon frame buffer, but
other reported the oposite.  I don't know why it failed for some with
the same kind of video chip.  It maybe a problem with the northbridge,
but I have no real evidence for this claim, only a rough guess.
