I have it working on my new 6000L, using the recent beta update of X/Qt. A number of the packages are optional, and some such as jp specific locales and fonts are unnecessary unless you use Japanese features. X/Qt alone on top of the basic ROM doesn't use that much space and should not be the main culprit if you are short on memory.
The problem I have found is that the X/Qt installation steps on Opera, which thereafter seg faults. This happened even after a hard reset and installation of X/Qt immediately over the factory default installation. Anyone else seen this?
