Bugzilla Bug 29636

contained in kernel include files. (Which is not present in the newer kernels) 

Reproducible: Always
Steps to Reproduce:
1.emerge -u apmd 
2. 
3.

The apmd-3.1.0 ebuild in bugzilla has the same problems.

APMD patch

Try the patch I just wrote [do a manual compile]. If it works, I'll commit
this in and fix the ebuild accordingly.

This patch cannot be applied to the version in the portage. However, if I
do the changes manually, it compiles without errors.

I know it compiles fine and I know it won't apply against portage, but does
apmd work properly as well? I just need to confirm that before adding the
patch to CVS.

Sorry, I can't tell you, because I have no APM support in my kernel right
now. I just encountered this bug while upgrading gnome - that was the reason
why I submitted it. Maybe someone else can tell more...

In CVS. I suppose if it compiles and works on 2.5 it should work fine on
2.6...
