Hey Rodrigues Bruno,

Here is an ubuntu compiled kernel that will work for the U43Jc
Headers: http://dl.dropbox.com/u/9907150/linux-headers-2.6.35-22-generic_2.6.35-22.33_amd64.deb
Kernel: http://dl.dropbox.com/u/9907150/linux-image-2.6.35-22-generic_2.6.35-22.33_amd64.deb

Then simply do:

echo '\_SB.PCI0.RP00.VGA._PS3' > /proc/apci/call

Be warned though, THIS IS ONLY FOR the U43Jc.

Sometimes you have to reset it again by running echo '\_SB.PCI0.RP00.VGA._PS0' > /proc/acpi/call and then run the above again...

This replaces the DSDT in memory when booting, I don't guarantee that it will work for everyone, but it works for me.

By the way, it looks like the post here: http://linux-hybrid-graphics.blogspot.com/2010/09/more-on-hybrid-graphics-for-asus-u43jc.html is just a complete rehash of what I posted on this site... Look at post 272 and 273 on this site...
