  Bounce buffers are required to DMA above the 16MB for ISA devices.
However, bounce buffers do not work for the aha driver (it is unclear
whether the driver or the bounce buffers are broken).

  This is any old problem.  See the archives.  It seems that any developer 
who has more than 16MB of RAM has also decided to upgrade to non-ISA
controllers.
