I find it very helpful to have the parameter visible in sysfs.
Given that:

[mst@tuck linux-2.6]$ grep module_param drivers/net/*c|grep [64]44|wc -l
14
[mst@tuck linux-2.6]$ grep module_param drivers/net/*c|grep [64]40|wc -l
0
[mst@tuck linux-2.6]$ grep module_param drivers/net/*c|grep [64]00|wc -l
7

So at least the precedent is against 0440.  What do you think?
