Author: mjacob Date: Thu Nov 5 18:25:26 2009 New Revision: 198959 URL: http://svn.freebsd.org/changeset/base/198959 Log: Unbreak SBus cards which have been broken (apparently) for a while. Most of the pieces came from Marius- correct settings for channels and resource management. The one piece missing was that you cannot for SBus cards replace 32 bit operations with A64 operations- not supported. This is an MFC of r198822.
