Please don't.  This is really corner case;  I at least wouldn't want GRUB
to install non-free blobs in /boot/grub automagically.

(Those blobs were already in the hardware, so GRUB is not responsible for
them, but still...)

Is this use case documented somewhere (e.g. in the wiki)?  Then users who
need it can learn about the procedure from the same place.  Also ...

... as Stefan points out (thanks Stefan) this may not be so
straightforwarded.  I don't think this kind of tweaking is suitable
for a setup that "Joe user" will get by default.

Btw, if the video rom can be obtained directly from memory, why doesn't
GRUB read it in runtime instead?
