Although I don't know in detail if and when these kind of cn=config 
settings will take effect (especially for changes), it seems to be 
supported:

Have a look at admin guide 2.4 and olcDBConfig attribute:
http://www.openldap.org/doc/admin24/slapdconf2.html#BDB%20and%20HDB%20Database%20Directives


BTW: Could someone confirm, that a slaptest -f -F conversion does not 
effect (aka ignores) slapd's bdb DB_CONFIG convenience settings like for 
example:

dbconfig        set_cachesize 0 500000000 4
dbconfig        set_lg_dir /extra/harddrive4performace
dbconfig        set_lg_regionmax 5000000
dbconfig        set_lg_bsize 5000000
dbconfig        set_lg_max 25000000
dbconfig        set_flags DB_LOG_AUTOREMOVE


In my case the above settings are contained in a "database hdb" section 
and although slaptest -f succeeds after running slaptest -f ... -F ... 
slapd.d's ldifs do not contain any olcDBConfig attribute.

Thanks!
