Issue with sarnia_entity_type not yet available in hook_entity_info

Hi
We're building an install profile that includes sarnia.
We're hitting some timing issues with the way sarnia uses the {sarnia_entity_type} table to store entity types.
Basically hook_entity_info is being called and sarnia_entity_info is running before drupal_install_schema('sarnia') is getting a chance to run.
What this leads to is an exception being thrown because the table doesn't exist.
The error is something like:

PDOException: SQLSTATE[42S02]: Base table or view not found: 1146 Table 'db.sarnia_entity_type' doesn't exist: SELECT label, machine_name,               [error]
search_api_server, search_api_index, id_field FROM {sarnia_entity_type};

Patch to follow once I've got an nid.
