Dear Luiz,

Thank you for your kind reply. I have already managed to start FreeBSD
on my board (and it runs much much better now; I suppose you're one of
the people I want to thank for that). I used the "old" method defining
"options FDT_DTB_STATIC". The only thing I'd like to add is that I also
added "makeoptions FDT_DTS_FILE=cubieboard2.dts" to the kernel config in
order to have it build.
