Sure, there may be justification for doing something like this
in the kernel, but the issue that started this thread isn't it.

The issue that started this thread can be diagnosed by user-space
in linuxfirmwarekit.  Multiple machines have this bug, which means
that it is "common industry practice" and the kernel has to work
around it (silently) if we like it or not.
ie. the issue, now that it is debugged and worked around,
is effectly just firmware lint.

thanks,
