I have red your email and wanted to say that I still use my psion 5mx with debian linux on it, I am even getting a 5mx pro in with 32mb !!! (so finnaly apt-get will work without swap etc...). if you have any question just let me know.
Am planning to build bluetooth in and to even update the ram to 64mb (I can not find the posting anymore with the gpio lines and manuals etc..)
