Thank you.

I tested 2.6.23.1 + 0.18-20071013, oops still there.  Should I test it
with the latest linux-acpi-2.6 git tree, also?  I don't think it's
necessary, but I can do it in case (but please read below).

Sorry, I'm quite lost with the git tree: in release/ there's nothing
about the latest linux-acpi-2.6 tree, what I can see is the different
linux releases with spare patches.  And if I correctly read the
README, I should check what's in for-upstream, which I don't really
know how to checkout with git (I performed a `git clone $TREE`).

Is it OK to wait to upgrade the BIOS until the bug has been fixed?
Because if the bug won't be present anymore with the new BIOS, we
don't have a way to be sure it's fixed.

Thx, bye,
