Just testing 2.6.38.2 now.  Seems as expected, no "Refined" line appears
in the logs.  I will look into perhaps extending what they did, but
using the pit timer, in my previous tests that gave good results at
around the 1s mark.

For the moment I need to move on to other development - Short term I
might just hack in a fixed offset into the kernel to get me by, however,
this isn't viable once we start supporting multiple devices. Hopefully
by then I can look into a better kernel fix

Thanks all
