Thanks for the pointer, I will try that. It is not a big issue for me, 
though, since ath works perfectly just OOB.

Don't mention it. The other big and still unresolved issue is getting 
SMP working. I have tried to debug it and as long as I can tell second 
core for some reason doesn't start at all. I have even attempted to 
borrow second CPU kick in magic from xnu (Darwin kernel), but the result 
is the same. My current guess is that since it's mobile processor, the 
2nd core may be turned off for power saving purposes and needs some 
(ACPI?) hohomagic to power it up. Unfortunately I can't find any 
documentation on the processor to check. It is interesting that both 
Linux and Windows don't have any problems with getting it working OOB.

The former. I think it should be possible to change partition type to be 
FAT temporarily, switch default operating system via MacOS control panel 
(see Boot Camp docco for details) and then switch is back partition type 
to FreeBSD, but I have not tried that.
