I've just tested and looked through code - module init callbacks
(init_module member of ngx_module_t structure) are called after
full configuration has been initialized (including logs) and even
debug works perfectly using cycle->log (once you have error_log
.... debug; configured at top level).

or init_conf callbacks of ngx_core_module_t structure.

You still should be able to use ngx_log_error(cycle->log), though
level is initialized to NGX_LOG_NOTICE by default (so it's minimum
level which will be logged unless you are reconfiguring already
running nginx).
