Author: marius Date: Wed Dec 23 20:42:14 2009 New Revision: 200915 URL: http://svn.freebsd.org/changeset/base/200915 Log: Don't probe the bq4802 variant found in Ultra 25 and 45 for now as this chip isn't MC146818 compatible and requires different handlers (but which I can't test due to lack of such hardware).
