If looks like you have Linux headers mismatching the kernel.
__netdev_watchdog_up() is used in netif_carrier_on(), which is defined as
inline function (I'm looking at Linux 2.4.25-pre7).  You should have
"__netdev_watchdog_up" in System.map.  See if it's exported by
net/netsyms.c in the Linux source tree.  Also see
include/linux/modules/netsyms.ver in the same tree.  It should define
__netdev_watchdog_up.

I've just checked that CVS HostAP works with versioned Linux 2.4.25-pre7.
