Default [Q] HTC Hero 2.2 - emergency calls

I recently rooted my phone and put the stable version of Cyanogenmod on it. I like my phone a lot better now, but there is one downside I can't seem to get past. There are 2 exchange email accounts that I want to connect to, but doing so forces me to enable either a pin or password for the lock screen. That also means that the emergency call button is right there on the lock screen.

I let my 18 month old son play with my phone. He is smart, but I know it is just a matter of time before he starts calling 911 from the lock screen. If it is possible, I would like to get exchange emails on my phone without needing the lock screen. Before the mod I was able to use Lockpick, but apparently that doesn't work with 2.2.

Does anyone know how to either override the need for a pin/password with exchange or at least get the emergency call button off of the lock screen? Thanks!
