Well, maybe modprobe is smart enough these days already, but openwrt
doesn't have it.
Anyway.
Circular dependency issue is now gone together with rfkill_backport
as I don't need rfkill at this point.
"Unable to reserve mem region" error was probably MIPS-related or
PCI-related and gone after cold reboot.

Now here is another:
 in function wiphy_register (net/wireless/core.c):
   device_add returns an error (-22)

Looks like some problem in mac80211<-->kernel_2.6.25 communication?
