Ok, I'll try to do something about that. Just want to tell, that some 
time ago, after this controller stopped to work in -current, I had dual 
boot system with windows. And when I was needed to burn some SD, I just 
booted to windows and successfully write SD.

I have a latest firmware for my laptop installed, so the only thing I 
can try is to boot some old FreeBSD versions to see if it will work with 
them, because this firmware can't be downgraded as far I know.
