Apart from KDE4, Gnome 2.26 will also be available in BeleniX 0.8. I pulled the Desktop Consolidation trunk (JDS) and built it with a bunch of changes. The packages are already available in the package repository trunk but not yet recommended to upgrade to trunk as it is seeing a lot of churn at present. One of the things pending is to replace the default OpenSolaris branding with BeleniX branding. Below is a screenshot showing Gnome 2.26 + Compiz + Avant + Google Gadgets + Webkit on my box. The Gnome developer help documentation browser is built with Webkit support.
