QuoteAlso, I'm not familiar with buffering, but if by that you mean put another chip on the line, that seems like it would be way too expensive,Do you want it to work or not?

You need buffering on the signals that go to all the chips when the driver can not cope with that number of inputs. Normally I would recommend one buffer to drive 4 chips. The buffer's inputs can be common.
Layout should be tight and short to increase signal integrate and reduce pickup and radiation.
Buffers are one of the cheapest ICs you can get. You get 6 buffers in one package for less than $0.20.
One of these buffers http://uk.farnell.com/texas-instruments/sn74lvc1g125dbvr/ic-buffer-gate-bus-smd-sot-23-5/dp/1470768 would take up very little space on your board.
