Sean,

Is this not within the Card display tab option...  you can then configure which attributes you want to display on the cards?

Non-list custom attributes can be made available to Planning by adding them to Attribute Mapping :
Open Project Area in Eclipse Client > Project Configuration > Configuration Data > Planning > Plan Attributes > Attribute Mapping > Add > Select the custom attribute and click OK

try this add those attribute you will able to see in you card
