Indeed. I'm not sure that the bootloader is a huge problem for many boards,
but the graphics hardware certainly can be, despite efforts to make genuinely
free drivers and firmware.

Yes, any subsequent laptops were only prototypes and probably borrowed cases
from other manufacturers' existing production models or had such things
commissioned by specific corporate customers. I knew someone who wanted to
put a motherboard from a newer generation of hardware into a laptop case, but
he never got round to doing that as far as I know. Dealing with the different
electronic components possibly isn't too hard if you know what you're doing,
as the following demonstrates (effectively achieving what my friend aspired
...but the matter of finding a suitable laptop body, particularly one that
might then be used to supply more than one unit, and making sure that it is a
robust solution probably poses the more significant challenge. That said, I'm
sure that there are people out there who could easily put the electronics
experts together with the product design and manufacturing experts, but a
random individual isn't likely to be so well-connected.

There is already stuff like the following available, of course:
That's architectually similar to the Ben NanoNote but, I imagine, not open
hardware nor currently manufactured.
