By AMS request, here is a bonnie benchmark between gnumach with and
without DMA. Putchar test has been disabled to make it faster (even
without this, it takes more than 2 hours each one).
Testing machine relevant specs:
AMD Athlon 700Mhz
SD-RAM 256M 133Mhz
IDE Controller VIA VT82C686
GNUMach *WITHOUT* DMA:
