which isn't on your system..... looking further:
( man -k udev ... play around with udevinfo ... )
$ udevinfo --query=name --name=/dev/misc/psaux --attribute-walk

Udevinfo starts with the device specified by the devpath and then
walks up the chain of parent devices. It prints for every device
found, all possible attributes in the udev rules key format.
A rule to match, can be composed by the attributes of the device
and the attributes from one single parent device.

looking at device '/class/misc/psaux':
KERNEL=="psaux"
SUBSYSTEM=="misc"
DRIVER==""
ATTR{dev}=="10:1"

No driver; looks like it's built into the kernel.

Yup, it was built into the kernel. (A module would have [=m])
