The only change to current stable is trivial: *polkit-gnome-0.96-r1 (11 Aug 2010) 11 Aug 2010; Samuli Suominen <ssuominen@gentoo.org> +polkit-gnome-0.96-r1.ebuild: Replace OnlyShowIn=GNOME; with NotShowIn=KDE; because polkit-gnome is useful also for LXDE, XFCE, and others. One sed line that makes it actually usable for Xfce4, LXDE, and propably others too. So no real testing required, you have already tested it ;-) Thanks
amd64/ppc64 stable
arm: You may want to stabilize this too, if USE=policykit is enabled, xfce-base/thunar will need gnome-polkit for authentication for mounting/other hardware stuff to work
Archtested on x86: Everything fine
x86 stable, thanks David
alpha/arm/ia64/sparc stable
ppc stable, the change was trivial
