Check your motherboard manual. It sounds like it is only caching the lower 16MB, either because of a setup option or because of a lack of cache memory.
Incidentally when I get my new page allocation finished it will, as a side effect, help such systems since it tends to focus usage on the DMA-able memory which, on an ISA class machine, is the lower 16MB.
