As mentioned elsewhere ro can be passed as a kernel option.

I did some testing. The network is brought up and configured in the d-i environment, not the rescue mode target's environment, so for my testing dhclient never got launched. Can you better describe the exact steps to recreate the problem? I think what you're really looking for is an option in the rescue mode dialogs to select whether mounting is attempted as ro or rw.
