I took a look at the isa_bus_dmamap_create() function and it looks like it
uses a flag-value to control bouncing behaviour. This can be changed/added
later as a value passed in the softc structure. If you can provide me with
the info about when to set this flag I will do so. I am however working on
the atari-pci version and have no access to i386 systems with adaptec.
If you have an AHA-284x card, maybe you are willing to preview/test the diffs?
Since I am building this on the first atari bus-dma implementation, some
beta testing on the i386 platform, where bus-dma is already implemented for
some time now, might be very appropriate ;-)
