I'm far from an expert but I know at least some power pc can do
unalign access, like those MPC8xxx, so the socppc port can do
unaligned accesses.

We support two kinds of architectures:
unaligned
strict alignment
In reality, we could write kernel emulators and make every
architecture be unaligned. In the worst cases of access, it would be
extremely expensive. Making a powerpc act truly un
Can PowerPC do unaligned accesses or not?
I'm bringing this up *again*, because the fragmentary dialog on ICB
about how powerpc is supposed to behave doesn't agree with observable
reality.
