Firstly during manufacturer and in order to cut costs during the availability of components, Commodore produced various revisions of Amiga 1200 motherboards. Only revision 1D1 boards are suitable for this type of heavy expansion. Later 1D4 and 2B boards are known to have timing problems with regard to the on-board Gayle and Budgie chips. Revision 2B boards are somewhat more prone to these aforementioned incompatibilities. These faults can be fixed on these motherboard revisions with some careful work with a soldering iron, but it is easier to just use a 1D1 revision motherboard in the first place.
Where did you get that quote from? The 1D4 and 2B boards were designed to take fixed versions of the Gayle and Budgie chips. However these chips were never made in the end and someone, somewhere, forgot / took a gamble to release the boards anyhow.
