fenair,

i feel your pain. the only way for me to access my schedule etc. on company website is to use (jurassic) SABRE applet that runs on java and to do that i have to run Iceweasel, a version of Firefox, off Easy Debian image.

instructions for ED are found here http://wiki.maemo.org/Easy_Debian

don't be intimidated by the wiki, read it carefully and follow the instructions. in no time you will have a "full" Debian OS running on your N900. after that, regardless of website, it will treat your N900 as a full desktop/laptop. you can thank "qole" for it, one of the smartest guys around on maemo.org.
