Dear Greig:

There are two ways: 1) boil colony which should be picked with pipet tips 
in 1XPCR buffers for 5min; 2)incubate colonies in small amount of 
zymolyase solution for 5min.  After the either way of breaking yeast 
cells, you could do PCR as usual.  It works fine.  By the way, I have 
used Pfu polymerase and its buffer (no affiliation to Stratagene), and I 
just haven't tested with other polymerases.  Theoretically there should 
be no problem with others.  Cheers!
