If I recall, LGPL was chosen to allow 3rd companies to write custom or proprietary plugins for Plex86, or to do internal device/driver development. It is one of the strength of open emulation/virtualisation.
By forcing these people to comply with the GPL, which wouldn't allow linking these proprietary plugins, we'd loose a major market share which could be quite helpful for new development.
