Manuel et al.,
I've tested these patches on a DB1200 board and they look good. I have
an Au1xxx IDE power management patch that depends on them that I can
release after they've been applied.
One catch - these no longer apply to the latest HEAD. Manuel, can you
re-spin and re-post them one more time?
