I'm afraid there isn't one in the kbd package available. The latest kbd, 1.15.1, only has six keymaps added compared to 1.14.1:
Colemak, German Intel based Macs, UK for the Sun Type-6 keyboard, French Dvorak, Kirghiz, cz.
The only us keymaps, in both kmaps.tcz and the latest kbd, are us and us-acentos.
If you have such a keymap, in either kbd or kmap format, I can add it.
