I've built a new kernel binary with the latest mac_scsi patches included. 
That is, the 23 patches that I recently sent to the scsi maintainers, in 
addition to the previous 84.

This version of mac_scsi implements working PDMA which should benefit 
68020- and 68030-based Macs (except for the IIfx). For example, sequential 
disk read throughput on my LC III is about fifteen times faster (when 
measured with dd).

The mac_scsi driver needs more work in order to support DMA on the IIfx 
and PDMA on 68040-based PowerBooks. (All of the other 68040-based Macs use 
the mac_esp driver and not mac_scsi.)

The download is here,

As before, this kernel configuration has the essential Mac drivers 
built-in so that it can be used without an initrd, e.g. for installation.
