They did manage to boot a modified firmware but there's still components
that aren't yet removed.
--it also removes all the modules from the images except RBE, KERNEL,
SYSLIB, and BUP--
So the modules RBE, KERNEL, SYSLIB and BUP are still their and if you
read correctly
--It should be noted that ROM, RBE, and KERNEL are executed at the zero
privilege level (in ring-0) of the MIA kernel.--
Has for the theoretical completely free firmware, only the future will
tell us.
But has I see things it would be faster to go on POWER and besides
faster we are 100% sure that there isn't anything in the background that
we don't know about.
Because has time goes on the X86 exploration we found surprise after
surprise.

They began to implement similar ME/PSP functions I unfortunately don't
remember the name of it so if someone knows please post it.
There's also the GPU problem, there is zero effort from allwinner to
free their MALI GPU and worse they persecute those who try to reverse
engineer it (see the LIMA driver developer) that's why no 100% free
driver is available.
But still recently there has been people who tries to do something about it.

I hope they'll be ok.

If you are interested in ARM I suggest that you go on the ARM-netbook
mailing list.
