Yeah, thinking about this further, it was a bad idea: it would break
Intel graphics support on systems that additionally have fglrx installed
in order to support a wider cross-section of hardware. For instance,
Valve's SteamOS supports all of proprietary fglrx, proprietary nvidia
and free i915 with a single OS image, and that blacklisting would break
their i915 users.
It looks as though Debian's kernels have AGP built-in rather than
modular since 2.6.32-10. You mentioned that you're using a non-Debian
kernel on an embedded device; if you're going to maintain your own
kernel anyway (e.g. if the 3.14 kernel in backports is not suitable for
you), perhaps you could do the same? If you can't reproduce this bug
with a Debian kernel (or a more Debian-like configuration) perhaps
#751275 can be closed as not affecting Debian?
Similarly, if you're maintaining your own kernel for this hardware
anyway, you could turn off all the CONFIG options for DRM drivers and
this wouldn't be a problem for you.
Failing that, a local blacklist seems like a reasonable solution for
your particular situation.
