LO -

With and without the "pea" kernel, using the backport modules, I got 
slower transfer rate speeds, as
reported by software during downloads, and notification of kernel errors 
on the desktop - which I didnt
forward using the bug report software. These kernel 'crash' errors 
occurred when booting with either
karmic kernel.

If your not needing any more information, I think I will remove the 
backport modules and cope with
the alternate module loading for a while.
