From GPLv3 section 6:
“Installation Information” for a User Product means any methods,
procedures, authorization keys, or other information required to install
and execute modified versions of a covered work in that User Product
from a modified version of its Corresponding Source. The information
must suffice to ensure that the continued functioning of the modified
object code is in no case prevented or interfered with solely because
modification has been made.

GPLv3 doesn't say anything about how the protection is implemented,
though it does say "continued functioning," so I think they've covered
this loophole. :) Once motorola (or whoever) ships the phone with a
GPLv3 kernel on it, they have to obey this clause. If they did the
proprietary binary thing, then they'd have to give you something that
allows you to use modified kernels... I'm not sure what that something
is, since I don't know if "method" and "procedure" mean "english
instructions," "source code", or "binaries" in this context.
