Don't enable/disable I/O space except for SAS adapters. This fixes a problem with VMware 4.5 Workstation. Fix an egregious bug introduced to target mode so it actually will not panic when you first enable a lun. Minor fixes: Take more infor from port facts and configuration pages. MFC after: 1 week
