I don't think so! I don't know anything about the av7110 spec.
I'll be happy with fixing module architecture for 2.6 kernel.
Anyway are you referring to reset_arm or what?

The two thinks are similar but not directly related:

the release callback should be passed in 

saa7146_fops.c : static struct video_device device_template

maybe this line alone can work (I didn't try it yet):

static struct video_device device_template =
{
        .hardware        = VID_HARDWARE_SAA7146,
        .fops                = &video_fops,
+      .release           = video_device_release,
        .minor                = -1,
};


regarding to power suspend the very first problem is that
sysfs info and callbacks for suspend and resume are located in the
pci_driver 
struct but av7110_init() and av7110_exit() don't use new struct pci_driver 
and pci_module_init()

The second and biggest problem is the actual writing of suspend and resume 
functions! ;)
I hope that one can use activation and deactivation code at first.

AFAIK udev use sysfs info, anyway udev it's still in developing.

Maybe someone else will fix them in meanwhile! 
Usb guys are quite active, I'm worried about lirc too but one has to start 
somewhere. ;)
