That PowerPC laptop project is never going to happen because they have
no money for it and it shouldn't happen because PowerPC is old and dead
- the new hotness is POWER and making a POWER laptop is entirely
achievable you can downclock one of the (4 threads/core) SMT4 4 core
CPU's to a mobile workstation level of for instance 50W of course
allowing users to re-clock to max on AC power.

To make a custom laptop you need millions in cash, it might as well be
something good.
