There is some misunderstanding here.
I had the negotiation problem, and as a result of this i started playing around
with DTrace on this machine and discovered that if I comment these lines my
drives were correctly detected. I posted this as a pointer/clue to the problem.
Then Justin replied, that the actual problem is in the aic79xx driver
not properly
exporting it's capabilites to CAM, and the latest revisions of
aic_79xx_osm.c > 1.30
fix this. There is no need to touch cam_xpt.c, just update
aic_79xx_osm.c, and the problem
should be resolved.
