It would show the resolved value of 0x2e, being "Expedited Forwarding" in the 
custom column.

That would required the option of having custom columns with unresolved values. 
An interesting concept in itself.

1.2.x was a bit different. There you had a program defined column type DSCP, 
which was filled in by the dissector with the unresolved value of the field.

The new development and 1.4 branch code tries to convert these program defined 
column types into custom columns in order to reduce the number of program 
defined columns.
Note that there's an error in this conversion in 1.4.0rc1, which is already 
fixed and scheduled for inclusion in the next release. Just so you know.

Thanks,
Jaap
