I could find no information no I only had the diff from the previous
kernel to compare against. I had been assuming that it would make its
way upstream from the original distro, I cannot say I understand the
issue well enough to test the issue myself which I would prefer to be
able to do before pushing this upstream.

Are they already available in reasonable numbers on market?

I do not see any problems with this. A blob in system is not best
practice, of course, but it does not need any configuration and is not a
performance bottle-neck, so there is no reason to care.

I personally would prefer AMD A8 if I can offload decoding to GPU unit
there (not sure if I can, so won't change my box till next summer), but
discrete video card will not be the most costly part in good non-gaming
box, hard drives will, so again, what the matter?
