Yes, but in return you'd be excluded from playing Quake unless
you're running one of those signed kernels or modules.

So, if I, say, want to test some TCP fix, new VM feature, file
system improvement, etc., none of the applications that rely on
DRM would work. This doesn't only affect developers, but also
their potential testers.

Given that most users will just run a distribution's kernel, with
all the right signatures, companies will not perceive the few
cases in which their use of DRM causes problems as very important,
so they will use DRM.

Oh, maybe some developers could be granted the privilege of being
able to sign their own kernels or modules. So if you're part of
this circle, you'd be fine, right ? No, even this doesn't work,
because if you'd leak such a key, you'd certainly get sued for
damages. And I don't think many people would feel overly pleased
with the idea of being responsible for the safekeeping of the key
to a multi-million lawsuit. (And besides, this may turn them into
targets for key theft/robbery/extortion.)

(There are of course uses of such signatures that would not have
those problems. E.g. signatures that prove trustworthiness to the
local user, instead of a remote party.)
