Yes, that's correct, both your assumption and the behaviour.

I think the "chkmin" script from PCA's "Contrib" webpage could help here. If you 
feed it the list of all patches from the CPU, it will reduce it to those which 
are not installed yet (in the specified revision or higher). You can then feed 
this reduced list back to PCA for installation. Something like this might give 
the wanted result:

   $ pca --install `cat cpu_patches.txt | ./chkmin`

Let us know if you try it!
