Wish you luck fixing the browser, but I have feeling that this is a dead end for microb without patching/recompiling. Yesterday I installed mozilla 1.1 and with little tweaking it has mouse cursor in web pages. Mouse is 100% working in mozilla. If anyone is interested here is how to show pointer in mozilla(1.1):

edit

/opt/mozilla/fennec-1.1/chrome/chrome.manifest

and add following line

override chrome://browser/content/cursor.css data:text/plain,<nada/>

Sure same effect can be acheved in a different way (even maybe on the fly), but some with more knowledge on mozilla should advice how.

Re poll questions -

showing/hiding mouse pointer can be done automaticly trough hal fdi script(think so ), so when mouse is paired/connected cursor to appear (and to disappear when unpaired/disconnected). What I am thinking is a control panel extension to select for which BT device[s] this to happen, so no end user has to modify scripts by hand.

lag that some people (including me before bluetooth.ko patching) have I'm 99 percent sure is due to bluetooth subsystem

BTW did you try bluetooth.ko and evdev_drv.so that I am using (those from attachment)? If yes - is mouse movement still erratic?

Cheers
