MS miss the check bounding in their AML interpreter, _but_
not in MS XP.  Though, your new brand model could potentially
have the exact same problem with this OS as well.  Really,
this up to Toshiba to debug their DSDT for their Satellites.
Actually, they have to cry to the real ODM, the real manufacturer
of allmost of their Satellite models, that is Compal.
(http://www.compal.com).

A 'real' Toshiba shipping a toshiba bios do not have this bug.
(it has others, but it was fixed by the help of FreeBSD team and
Intel)
