The star of the Zaurus Clamshell world, Meanie, has created a beta of PDAXrom intended for use on the Zaurus SL-C3000. There are problems putting the regular PDAX on the 3k because it lacks space in flash (It was originally designed to run everything off of the HD, thus it only has 16mb of flash, vs 128mb for all the other SL-Cxx00 models). It's built on the base of the previous 2 betas of PDAX that were made for the 3k, which were based on PDAX beta 1.
Meanie has taken the 3k 2nd beta, combined it with last "stable" PDAX with the 2.4 kernel, beta 3, and made most of it work flawlessly. There are a couple of outstanding bugs, though, so I've set up a page for my notes over at SDI, The Homepage.
