ndis-based network driver fails to load at boot (8.2-PRERELEASE)

[Yuri]

I have the old module that always worked.
Begining from some update (~8.1-STABLE), it stopped loading at boot time 
with the messages:
<...skipped...>
module ndis already present
KLD file bcmwl5_sys.ko is missing dependencies
<...skipped...>

/boot/loader.conf has this line that is supposed to, and was loading the 
module:
bcmwl5_sys_load="YES"

Rebuilding the driver from Windows version with the current ndisgen 
doesn't change anything.
Loading this module by hand (kldload) after system boots succeeds and it 
runs fine. Although it also says: module ndis already present

Why it fails to load at boot?
