            Bug ID: 214670
           Summary: MCS9900-based parallel port card unsupported
           Product: Base System
           Version: 11.0-RELEASE
          Hardware: Any
                OS: Any
            Status: New
          Severity: Affects Some People
          Priority: ---
         Component: kern

It seems that due to an oversight, parallel port cards with the MCS9900 chipset
are not supported by the FreeBSD kernel. After adding the following patch and
adding appropriate device hints, the card is supported and works fine:

 };

Please add this patch to the FreeBSD kernel so the card is supported
out-of-the-box.
