James, your sim710 changes look nice, but I think there's some more
stuff to do in this driver.  I've started with the following (all
untested due to lack of the hardware):

  - move to scsi_add_host/scsi_remove_host interface
  - remove a bunch of unneeded ifdefs
  - add missing statics
  - unregister driver templates on unload

and I think there's more that should be done, but this would change
user-visiable attributes:

  - remove the ugly single module option code and the command line
    parsing in favour of Rusty's new module_param stuff
  - split the driver into two drivers: 53c700_eisa and 53c700_mca.
    There's no logic shared between those two busses, just a little
    bit of helper in the setup/remove code

And after looking a this driver I have some rants about the new
mac/eisa code:

  - mca_register_driver/mca_unregister_driver should check for
    the precense of an MCA bus by themselves instead of leaving
    it to the caller
  - eisa_driver_register should really return 0 for sucess
  - mca_register_driver/mca_unregister_driver should be named
    mca_driver_register/mca_driver_unregister to be more similar
    to the other *driver_(un)registers.
