He estado intentando hacer funcionar el Camera.apk de Froyo Ultimate que tú dices, y tristemente tienes razón, no tira ni a patadas, pero he aquí la razón técnica (esto es lo que aparece por logcat al intentar acceder a Camera):

De lo que deduzco que el problema no reside en las librerías ya compiladas (he probado las relacionadas con la cámara de Froyo Ultimate y aún así no va), sino en el fichero
Camera.java del código fuente de Froyo. Por lo que, me parece, que el único modo de hacer funcionar esa aplicación sería recompilar de cabo a rabo toda la ROM, con cuidado de que no pete nada y de que estén todos los métodos presentes para su correcta ejecución, cosa bastante más complicada de hacer que mover archivos de una ROM a otra.
Así que si alguien con más conocimiento y experiencia con Android y Java se anima, bienvenida sea su aportación.
Por último, me alegra comunicarte que he encontrado un atajo para silenciar el teléfono desde la pantalla de bloqueo. Consiste en desbloquear la pantalla con ENCENDIDO, y después presionar simultáneamente VOLUMEN ABAJO + ENCENDIDO durante 1 a 2 segundos hasta que aparezca el menú desplegable del botón ENCENDIDO. Para volver a poner el sonido bastaría con hacer lo mismo con VOLUMEN ARRIBA + ENCENDIDO. No es que sea una solución muy elegante, probablemente no te saldrá a la primera y cuesta saber si se ha silenciado o no correctamente, pero ya es algo.
Otra manera menos liosa y tanto o más discreta de hacerlo es presionar ENCENDIDO durante 2 segundos y directamente elegir "Modo Silencio". Al menos haciéndolo de este modo se ve reflejado en la barra del sistema.
Saludos.
