*gulp* I'm a little embarrassed to answer now.... nah not really
ok, for Browsers try www/konqueror-embedded and www/minimo, you mentioned lynx but try links+ since it has a nice fast graphical mode but is essentially a text browser. For x11 based browsers I suggest the first two mentioned.. Firefox is too darned big (runs at about 46Mb) and has some build issues that nobody can be bothered to sort out because it's too darned big. Mozilla suffers from the same problem as Firefox and therefore so does Epiphany since it is based upon Mozilla etc.etc.
As far as Windows Managers/Desktop environments etc..
xfce4 will give you a full desktop environment - be warned though it is a little memory hungry and you may wish to try all of the tunings that I suggest in the Performance tuning the 'Overburdened Zaurus' thread... it does take some time to build everything for this too. - Practically I have it built, run it from time to time but if I want to run anything meaningful on the Zaurus I quit it and use...
fvwm - yes the standard thing that comes with OpenBSD is actually pretty darned good with a mouse connected the only criticism really is when you get new Windows appearing that sometimes they appear with the top of the Window offscreen and it is awkward to move things around if you don't have a mouse connected which leads to the third suggestion...
ratpoison - for pure geeks that want X facilities but won't put up with the loss of resources on meaningless eye candy. ratpoison can be driven entirely from keyboard. it is a very powerful Window Manager, uses minimal resources and works very well for a variety of applications that you may want to run on the Zaurus.
