well, i won't pass up a free beer, but my code didn't do it. :)

you have a 486-class machine that doesn't have busmastering IDE.  it's
not even a PCI bus machine.  you just happened to turn on the
already-existing multi-block and 32-bit PIO flags in your latest
kernel upgrade.

folks: performance with the default flags on the wd driver is
*terrible*, and the flags should always be configured for your
machine.  see LINT for details.

Predictably, they all eventually wandered away, rubbing their bruises
and brushing mud out of their hair.  Some went off to work for the
ESA, launching much smaller rockets into low orbits, while others
elected to sit on their front porches drinking Jim Beam from the
bottle and launching bottle rockets from the empties. [Jordan Hubbard]
