No, it won\'t. Currently the Cacko rom is not available for the SL-5600 (or SL-5500) Zaurus.
Maybe the Cacko team will port it in the future.
The Sharp Rom, the Kompany Rom, and OpenZaurus Roms are available for your
platform, should you wish to try them instead. X11 can be made to run on these Roms too,
and additionally Zaurus-Debian (pocketworkstation.org) with X11 can run as a \"guest\" OS
sitting on a Zaurus which has another Rom installed.

Edo.
