So do you think this will be patched soon by google?
It's not a google problem. OS X itself is enabling the GPU when certain libraries in OS X are called.
Yes, you can probably stop chrome enabling it by turning off chrome features, but that is side-stepping the real problem.
The GPU auto switching in the MBPs is mildly retarded.
IMHO - on battery, the discrete GPU should be turned off 100% of the time. You get horrible battery life with it enabled - and anything that requires it to run well will kill your battery in under an hour anyway.
The MBAs and other macs get by without a discrete gpu for most of the tasks i use my machine for on battery. There should at least be a tickbox in the power settings for "force integrated graphics on battery" or similar.
(yes i know about gfxcardstatus. doesn't mean apple shouldn't fix it themselves)
