Pull up revision 1.82 (requested by thorpej in ticket #553):
- When starting an ATA or ATAPI transfer, handle the case where (*dma_init)()
  returns EINVAL, indicating that DMA cannot be done for this transfer.
  Fall back to PIO in this case.
- Add a geodeide_dma_init() routine that checks to make sure that transfers
  start on a 16 byte boundary, returning EINVAL if not.  Works around a chip
  bug that causes a hard system hang.
Problem reported and patch tested by Erik Fair.
