I needed to teach myself how to compile, and it paid off. I have Fluxbox 1.0.0 running perfectly on my Akita pdaXii13 Zaurus. This version of fluxbox is apparently faster than the 0.9 branch. Window move via ALT-LMB and window resize via ALT-RMB (that is, ALT-FN-LMB) works flawlessly.
Pixmap styles can be loaded. Also, styles seem to load much faster than for Fluxbox 0.9.1.2, which is what I was using until now.
This WM is extremely efficient and stable, plus a pleasure to look at and work with in the Zaurus. It will make your Zaurus run faster, and probably will also make you more productive (this is just a subjective opinion, though.)
The release will come later today. This is for a 2.4.20 kernel, so it should be fine for pdaXrom 1.1 Beta1, Beta3, and pdaXii13 (what I got running now.)
I got gkrellm running with full transparency (0.9.1.2. had an issue which caused a 1 pixel frame to be rendered around it.) This setup looks great. I will post some screenshots later, and will tidy up the IPK and get it ready for distribution later today as well (made a mistake and installed to /usr/local/ instead of /usr/, so I need to repackage.)
