no they doesn't, but here is a part of pxa2xx-flash.c and driver 
structure registered by driver_register call. Is it problem ?


static struct device_driver pxa2xx_flash_driver = {
         .name           = "pxa2xx-flash",
         .bus            = &platform_bus_type,
         .probe          = pxa2xx_flash_probe,
         .remove         = __exit_p(pxa2xx_flash_remove),
         .suspend        = pxa2xx_flash_suspend,
         .resume         = pxa2xx_flash_resume,
         .shutdown       = pxa2xx_flash_shutdown,
};

static int __init init_pxa2xx_flash(void)
{
         return driver_register(&pxa2xx_flash_driver);
}

static void __exit cleanup_pxa2xx_flash(void)
{
         driver_unregister(&pxa2xx_flash_driver);
}

On 2.6.24 kernel driver structure register the same way but sleep mode 
works fine there.
