PROGRAM= is used to return a string that can be matched against with
RESULT=, or be used to set the name of a node with %c. You should not do
anything else on with a callout.
On "remove", udev will remove the node for you and no callout will run.

Kay, let me rephrase my response.
The output of my script is the following
# ./* fd0
fd0 b 2 0
fd0u360 b 2 12
fd0u720 b 2 16
fd0u800 b 2 120
fd0u820 b 2 52
fd0u830 b 2 68
fd0u1040 b 2 84
fd0u1120 b 2 88
fd0u1440 b 2 28
fd0u1600 b 2 124
fd0u1680 b 2 44
fd0u1722 b 2 60
fd0u1743 b 2 76
fd0u1760 b 2 96
fd0u1840 b 2 116
fd0u1920 b 2 100
fd0u2880 b 2 32
fd0u3200 b 2 104
fd0u3520 b 2 108
fd0u3840 b 2 112
What would my udev rule be?

This does not fit into the udev model. We can only support devices that
have a sane sysfs kernel representation.
You may call MAKEDEV it with a dev.d/ script triggered for the fd*
device.
