Indeed, running latest OpenWrt release is the fix, yes.

Hold my beer.

You can't beat gdb+opencd.

SoftICE is actually something different, it's like kernel mode debugger, so you could essentially freeze the running kernel at any time and poke into the system internals.

It's almost there </sarcasm>:

That's really terrible recommendation. You should add firewall rules and allow SSH access only from trusted hosts, ideally over VPN. It's not about login attempts but about possible bug in SSH (and other network services), because it's all just software, written in C, so believe it or not, but it's there, it's not if but when.
