Yes, you can :)

I used Maurizio Sartori's noarp module, suggested in your HOWTO in
chapter 4.5.3. It can be controlled by IP, not by interface. 

I don't think the module is related to my problem. I haven't seen any
arp requests related to the freezes. And the working part of the source
looks quite simple.
