Change in how to apply Patch with SCCM Client push

There used to be a couple of articles online explaining how to add the PATCH=... command to the Client Push installation properties, but those articles have disappeared.  I also began seeing error 1635 on machines trying to install with that argument.

The new way to add a patch, such as http://support.microsoft.com/kb/977384, is this:

In the Client source folder (%installdir%\Microsoft Configuration Manager\Client) create a folder called ClientPatch.  Copy the .msp file into that folder.

So it looks like this:
E:\
    Microsoft Configuration Manager\
          Client\
                ClientPatch\
                        sccm2007ac-sp2-kb977384-x86-enu.msp

That's it.  SCCM will automatically try to install any .msp files you put in that folder when the Client is pushed to machines.  Once I changed to that and removed the PATCH argument, my client pushes started working again.
