In fact this is wrong, it's the worst case time - the ccache cache was
cold. With subsequent runs it does in fact go down to about 1 hr, which
proves the value of ccache.

Yeah I am aware that cross compiling would help. I don't have any other
PowerPC hardware to hand.

The Barcelona SDK is available in Ubuntu's repositories but it's out of
date and fails to build the kernel for some reason. I may still update
it but seeing as gcc 4.3 and binutils 2.18 in Intrepid now include Cell
support I felt it may be better to try to get a cross tool chain built
from those sources so I'm test building the kernel with the same
toolchain that Ubuntu's build daemons will be using. I managed to get
binutils 2.18 built for cross compiling but I'm stalled on a gcc compile
problem.

Is this because the hypervisor doesn't expose it to Linux or is it
because no driver exists for it yet?
