okok I give up ;-)
Here is the first attempt of an Ixus55 port for firmware 1.00B and 1.00C based on the latest Allbest trunk as of today:allbest_ixus55_100bc.zip - 3.56MB
You can find the compiled firmware in bin/1.00B and bin/1.00C.
Please note that this version still seems somewhat buggy: Histogram and Zebra mode do not behave correctly (they did in the allbest trunk as of beginning of February). But I am too tired to find out the reason myself currently... ;-)
Raw shooting, scripting, etc seems to work though, so please test this version and post all bug-reports in this thread.
Hopefully we'll have a stable version soon that can be included into the CVS.
@mungler: Please keep your money ... I do have a (more than) full-time job already ;-))
