As far as I can see, the symbols in question are not defined as inline:

compat/compat-2.6.26.c:
  EXPORT_SYMBOL_GPL(dev_set_name);
  
compat/compat-2.6.26.h:
  extern int dev_set_name(struct device *dev, const char *name, ...)
                        __attribute__((format(printf, 2, 3)));
net/rfkill/core.c:
  EXPORT_SYMBOL(rfkill_blocked);

include/linux/rfkill-backport.h:
  #if defined(CONFIG_RFKILL_BACKPORT) || defined(CONFIG_RFKILL_MODULE_BACKPORT)
  .......
  bool rfkill_blocked(struct rfkill *rfkill);
  #else /* !RFKILL */
  .......
  static inline bool rfkill_blocked(struct rfkill *rfkill)
  {
        return false;
  }
  #endif /* RFKILL || RFKILL_MODULE */
  
config.mk:  
  ifdef CONFIG_COMPAT_WIRELESS_31
  CONFIG_RFKILL_BACKPORT=m
  ......

Maybe module loader is supposed to do some magic with symbols, which openwrt 
is missing? However, other modules work just as usual, there are no problems
with lib80211* for instance.
