you have to adjust the path...
same can be done unter Administration->Client Installation Settings->Client Push Instatallation Properties
you can even add multiple patches like this (this is tha same like in sccm 2007):
PATCH="\\server.local\SMSPKGD$\VIE00003\i386\hotfix\KB977384\sccm2007ac-sp2-kb977384-x86-enu.msp";"\\server.local\SMSPKGD$\VIE00003\i386\hotfix\KB2509007\sccm2007ac-sp2-kb2509007-x86-enu.msp";"\\server.local\smspkge$\VIE000BC\sccm2007ac-sp2-kb2698619-x86-enu.msp"
