Seems that the kernel doesn?t insert the hostap.ko because it was 
compiled with a newer GCC.
Apr 17 14:50:24 localhost kernel: hostap: version magic '2.6.10
PENTIUMII gcc-3.4' should be '2.6.10 PENTIUMII gcc-3.2'

Maybe it has to do with MODULE_VERSIONING (CONFIG_MODVERSIONS)
Try to recompile your kernel and hostap with the same compiler.
Or try to load with insmod -f
