By and large you can't do without it. It supplies a Qt3 interface from Qt4 so 
that Qt3 apps can run on Qt4.

Note that it has nothing to do with KDE per se and everything to do with Qt. 
You likely have quite a few Qt apps that are not from KDE (skype comes to mind 
but I forget which Qt it uses nowadays).

Try remove it by all means. If the ebuilds don't whinge it's worth a try. What 
have you got to lose? Compile Qt (about an hour), revdep-rebuild (another hour 
maybe) and some testing. BOINC will lose out on some cycles but there's enough 
users out there to take up your slack :-)
