Hey, why not shared memory? Any memory block once allocated can be remapped
in user space (if it starts and ends on page boundary). The only problem with
ISA DMA it to actually GET unfragmented block of 32-64 KB size below 16 MB.
If you press Shift-ScrollLock you will see the statistics of available blocks
(run dmesg after)
