Please name names, otherwise this is just rumouring. Seriously. We have enough cargo-cult programming as it is.

A lot of old ISA systems had an option to put a memory hole at 15-16 MB to support ISA video cards with linear frame buffer. It very rarely got used, since VLB took over around the same time.
