You can find the patches here: http://kubuntu.org/~jriddell/kdeprint
I'm fighting with kdelibs on the iBook right now but tomorrow I'll start working on this.
It appears that the way gentoo is packaged these patches are needed for kdelibs and are already in the ebuild. Just need to remerge kdelibs after unmasking and upgrading to cups-1.2.
Yes, forgot to close this bug up after adding them.
