Bug#290039: kernel-image-2.4.27-1 ACPI Fix

[Horms <horms@debian.org>]

Hi,

I have put up packages for testing that include the attached patch which
I believes resolves each of then following bugs:

#290039, #290013, #289517, #288712, #285521

The packages are at the URL below and represent what will become
the official 2.4.27-8 packages, though there are a few additional
bugs that need to be investigated first. I you have a chance, please
test them out.
