Hey! the sentence 'It permit to EOMs to break ACPI support under Linux' is
a more a gratuitous Troll!

Actually, there is certainly no real support for free-like OS, because there
is not enough users, compared to the non-free OS users on those laptop.

The trouble is the internal management of the laptop.  OEMs have to check
that it work for the provided OS.  For example, if we wake on a Toshiba
3000-100, the mouse is not reset correctly.  If we say that we are on 'NT',
the mouse now work as expected.  Why *exactly* ?  I don't know, but
I suspect that a SMI handler was launched by the system in order to
correct the issue for NT, but not for windows.
