Very interesting, this will come in handy. I managed to find a 16 MB RAM module, bringing my RAM total to 32 MB. Installed 5.4 and boots fine, no problems. X doesn't work due to a lack of RAM causing swapping (which slows the laptop greatly), but maybe dmassage will help get rid of some device drivers and help the situation. Thanks for your help.
