Well, Ubuntu probably isn't the place either.
The actual hardware drivers from the Linux Wacom Project are pretty much feature complete now including OLED support for the Intuous 4. Jason just committed a bunch of patches to fix the long standing button mess. If they survive testing and review then configuration gui's can finally ignore the difference between the physical ExpressKey number and what X is using as the number. Plus use out of sequence keys.
So once Jason's patch to libwacom for the new xf86-input-wacom button handling is committed then gui's can finally handle tablets with out of sequence keys like the BambooPTs.
This means the Gnome configuration gui should improve dramatically shortly. And any other gui or app that decides to use libwacom for tablet metadata.
The people responsible for the configuration gui's are the Desktop folks like Gnome and KDE. Or any third party that wants to jump in and write a gui.
However I think you're still stuck with Karg's app for OLEDs. He did update it after all. If I remember correctly Bastien, the Gnome developer doing the heavy lifting on the Gnome Wacom tablet app, isn't planning on adding OLED support. At least not soon, but I don't recall the details other than it didn't sound real encouraging. But at least one LWP devel Przemo (who added Intuous4 wireless support) was interested in looking at it. I don't know what the plans are for the KDE configuration app OLED wise.
