I just investigated a bit further. This is a diff of debian/nut.postinst
between trunk and lenny package source:

Funny enough udevadm is missing in etch and udevtrigger is missing in
lenny :)
I think, if this is the only reason to have udev version >= 0.124-1 it's
much better to fix this by checking which binary is present. And remove
this explicit version dependency :)

P.S. Chacked the bug #489831. Seems it is indeed the only reason!
So I suggest this fix for lenny:
