Well, you don't really expect Ultra-SCSI to make much of a difference with the IBM DORS anyway, do you ? ;-) Since Ultra-SCSI requires extremely short and good cables, I decided to add 53c875 support with Ultra disabled, in order to be sure that problems reported would not be caused by marginal hardware. I'm just testing the Ultra negotiation on my system (based on own modifications and patches sent by Gerard Roudier), and will most likely commit them to the -current repository before the end of the week.
