Matthieu must have rebased his yahoo patches recently.  The copy I have
registered his old driver as:

+	// DIO_6 on TS-72xx header
+	#if defined(CONFIG_EP93XX_PWM) || defined(CONFIG_EP93XX_PWM_MODULE)
+	(void) platform_device_register_simple("ep93xx-pwm", 1, NULL, 0);
+	#endif 

When I submitted the updated pwm driver I didn't add the code to register
the pwm peripheral in any of the platform init's.

If you want to use the pwm signals just add the ep93xx_register_pwm() call
to your init_machine().
