I just did an 'ACCEPT_KEYWORDS="~x86" emerge gnome' yesterday, and gnome-volume-manager (along with the dbus stuff) /didn't/ get installed with the rest of things. The main features of GNOME 2.8 that most of the review sites are touting are the VNC server and the automounting stuff, so it'd probably be a good idea if gnome-volume-manager got installed with the rest of the 2.8 stuff.
You need to have use=hal. Also, you shouldn't run ACCEPT_KEYWORDS="~x86" as portage will try and downgrade everthing on your next emerge. man portage and look into the /etc/porgage dir for adding keywords to specific packages.
Ahhh, USE flags thwarting me again! Thanks. :) As for the ACCEPT_KEYWORDS thing, whenever I do upgrades I use "emerge -Uu", which seems to avoid downgrading. When I'm using ACCEPT_KEYWORDS, it's usually because I don't want to always be using the unstable version of a package, it's just because I want to move to a specific release version before it's made stable. Once gnome-2.8 is stable, I want to stay with that, not keep upgrading to whatever's currently available and unstable. :)
