(after looking at the code again) this translates to 
- use autoincrement -> look for a mode "autoincr", if not found use
  "manual" as shorthand for the module
- use the shorthand "auto" as name to locate the actual module that
  implements the autoincrement feature

Therefore you need to have in cocoon.xconf:

   <component-instance logger="" name="auto" class="org.apache.cocoon.components.modules.database.ManualAutoIncrementModule"/>

as the only component instance with the name "auto".

If you change <mode name="manual"..../> you would need to have

   <component-instance logger="" name="manual" class="org.apache.cocoon.components.modules.database.ManualAutoIncrementModule"/>

in cocoon.xconf instead.

Another option is to change your table-set:

  <table-set name="foo">
     <table name="bar" autoincr-mode="my-mode"/>

and have in database.xml

    <mode type="my-mode" name="whatever"/>

and have    
   <component-instance logger="" name="whatever" class="org.apache.cocoon.components.modules.database.ManualAutoIncrementModule"/>

in cocoon.xconf

If this doesn't work for you, please post / send me your sitemap.xmap,
the database.xml and cocoon.xconf (relevant parts only). In addition,
you could try to set the debug level in logkit.xconf to "DEBUG" for
the sitemap and look into sitemap.log. The actions should be relative
verbose on what's going on.
