Hi Len
Another resend in case this has been lost for some reason.
This patch (mostly from Peter Gruber) against 2.6.27-rc4 (but with the
interim P8010 patch from 2.6.27-rc6 applied) improves the handling of the
hotkeys for P8010 laptops by passing more accurate input events back to
userspace. This is needed because the P8010 labels these buttons quite
differently to earlier laptops. As part of this, a P8010-specific DMI
callback check has been implemented. Finally there's some minor whitespace
cleanups from running the source through Lindent.
Please apply to acpi-test for 2.6.28.
