You are not. I have a friend who described the same problem you did, but he
has an vaio laptop, I don't know what model, but with those same dual video
chipsets...

He said battery lasted about 6 hours on Win7 and 1.5 hours on Linux... He
said also that the battery on Win7 lasts less with Radeon Video activated...

What I think that might be is, a drivers problem, maybe they are not as
refined as they are on Win7, and the OS is not capable enough to control
the hardware to save energy, that might have been spent on the unused video
card...

...

Can you do a dual boot? I'm really curious to see how this works on
hardware, are the two video cards activated (available) at the same time?
Or the BIOS controls that by itself? I guess that activating the video card
with that button, and doing a *$ sudo lshw* and after that deactivating the
video card and again* $ sudo lshw* might answare this question...

PS: I can't say nothing about the performance. All other problems you
described might be a drivers issue too. Another thing... a live CD might be
ok to do those test I suggested you to.
