Put the tiny folder in the usual place (under the hardware folder). Then move the contents of the tiny folder into a subfolder named 'avr'. So for example my tiny files are located at:

...\arduino-1.5\hardware\tiny\avr

Then, copy the "platform.txt" file from:
...\arduino-1.5\hardware\arduino\avr\platform.txt
To:
...\arduino-1.5\hardware\tiny\avr\platform.txt

And voila, that should be all it takes. Restart the IDE and away you go.

The good news is that my fix for tiny85's and tiny84's to prevent errors when the compiled size is greater than 4kB still works in Arduino 1.5.1:
