When attempting to emerge alsa driver it complains about the PM_LEGACY feture
being turned off in the kernel (my kernel is 2.6.16_rc1). According to ALSA's
Changelog for 1.0.11rc3 this kernel feature is no longer required...
Snippet from alsa's site for the 1.0.11_rc3 changelog:
http://alsa-project.org/changes/v1-0-11rc2--v1-0-11rc3.txt
+ ALSA Core
- Fix compile on 2.6.15 without CONFIG_PM_LEGACY
This also applies to later kernels (tested with 2.6.16_rc1)
Commenting out that section in the ebuild and issuing "emerge
alsa-driver-1.0.11_rc3.ebuild digest" and then emerging alsa-driver installed
without a hitch, and functions fine. It seems that the PM_LEGACY check is not
longer necessary and can be removed entirely.
