I didn't test all the configurations (but sooner for my test it was in stamina 
mode).
And in fact, with my laptop,  I don't need to boot an old kernel, and it 
doesn't matter what the switch position is, as the screen always light up at 
first time since Linux 2.6.33 in my case (and X always choose Intel driver -- I 
haven't tried nvidia proprietary driver since 2.6.32 when I've got black 
screen issues and didn't do too much googling on the subject).

Moreover, in my case, no need to add acpi_osi="!Windows 2006"

I just write a mail to Len Brown and Dave Airlie (CC to LKML), maybe they 
could have some ideas ?!
