Hi,

the kernel team has announced this already some time ago, but there are still 
some ebuilds in the tree using kernel-mod.eclass in there latest version:

sci-misc/comedi/comedi-0.7.68.ebuild:
  herd:  no-herd
  dev:   caleb
media-video/mplayer/mplayer-1.0_pre7.ebuild:
  herd:  video
net-firewall/tuxfrw/tuxfrw-2.58-r1.ebuild:
  herd:  netmon
  dev:   angusyoung

Please convert your ebuilds to linux-mod.eclass.
You can find help at the top of the eclass and in the #gentoo-kernel irc 
channel.

For the full list including older versions of pkges see:
http://dev.gentoo.org/~genstef/files/remaining-kernel-mod-ebuilds

If you maintain one of those please remove them from the tree and mark newer 
versions stable if applicable.

Regards,
Stefan
