The backup program should not backup INFORMATION_SCHEMA at all (it is mostly statistics that not stored persistently anyway, no need to backup/restore it, restore of it does not make sense)

I agree it does not feel right, and needs to be fixed. By also take into account that disabling innodb is not something people do often, in contrary overwhelming majority runs innodb all the time.

If you would like to remove all trace of Innodb/XtraDB, and do not like to switch off all information schema plugins individually, use "ignore-builtin-innodb". The documentation of this variable here http://dev.mysql.com/doc/refman/5.1/en/innodb-parameters.html is rather sparse, but it does disable all of innodb.
