I *think* around that time, there was a fix for S3 resume behaviour, and I
*think* that made one of the previous ugly hacks from hell we used on the
T43 a hindrance instead of a help.

That might well have been on 2.6.25.y, I will check my T43 when I am back at
home and reply.  I never labelled it instability in my mind, because all it
caused me was a slowdown that I quick fixed at the time.

Thanks for reminding me about this whole deal.  As I said, I will get back
to you when I find out more of what I did that never make it a big deal for
me.  *DO* note that I do NOT use Tux-on-Ice or PHC.
