Looking at this, seems there's the command line param, and 
swing.properties in jdk's dir, which would need to be changed after each 
jdk reinstall though, some equivalent file in $HOME/.java or similar 
would be nice but I'm not sure there exists one.

Command line param should be somehow possible with gjl-based launchers 
for java applications installed through portage. The launcher will 
source files in /etc/java-config-2/launcher.d/$package and 
~/.gentoo/java-config-2/launcher.d/$package
(see /usr/share/java-config-2/launcher/launcher.bash)
Declaring something like gjl_args="-Dswing.defaultlaf=$foo" there should 
be eventually passed to the java process.

Won't affect running java manually though, and it's hacky. Certainly 
room for improvements, suggestions welcome.

I think gmane.org can search through archives of mailing lists including 
this one, but I don't recall such question myself.

Sure, one day :) openjdk builds are available in java-experimental 
overlay, but it's time-consuming to maintain them and we could surely 
use more people dedicated to that...
