How to style text in action overflow menu on device with Android>4.0 and hardware button?

I would like custom background & text color for my overflow menu. It works fine with devices without hardware menu button, but I'm not able to style devices with hardware menu button. See the screenshots:

I'm using these styles:

<style name="Theme.settleup" parent="@style/Theme.Sherlock.Light.DarkActionBar">
    <item name="android:popupMenuStyle">@style/settleup_PopupMenu</item> 
    <item name="android:actionMenuTextColor">@android:color/white</item>
</style>
<style name="settleup_PopupMenu" parent="@style/Widget.Sherlock.ListPopupWindow">
    <item name="android:popupBackground">@drawable/menu_dropdown_panel_settleup</item>
</style>
