kde4.0.0, co-existing with kde3, on slackware-12.0
http://batts.mine.nu/downloads/slackpkgs/kde4.0.0/
check it out, and tell me where it breaks. i can not be responsible for this breaking any kind of your install, but if if does, do tell
this is very, very, to me. on my wife's laptop, it boots to a kdm console, where you can choose your session like normal, and kde4 is an option now!! and kde3/qt3 never have to get uninstalled.
