All Ive done is flashed the EB01 Froyo.
The Stock EB01 contains a kernel that will play the stock boot animation file (bootani.qmg)... it is not set up to play the (zip) file... to get the custom bootanimation.zip files to play you will have to flash a froyo kernel of your preference (see links) - then you will have to delete the stock (bootani.qmp) file from your system media folder or you will have boot animations playing on top of each other...
Hope this helps.
