I didn’t know it was release day, my timing is not perfect then, sorry about 
that, I didn’t intend to put stress on you guys today.
Like you mentioned, the Linux boot protocol doesn’t mandate any loading 
address, hence the possibility to set it on the command line. 
It would benefit not only to FreeBSD (which is strictly Linux boot ABI 
compliant BTW - that is how I found the qemu bootloader bug and fixed it in 
b4850e5) but all other OS.
On the real hardware Raspberry Pi, there is the kernel_address firmware feature 
which enable to set the kernel load address. Would be neat to have it *someday* 
in qemu for any board if it is not too hard to implement.

Again, I didn’t know about the timing. Indeed it is a bug but I let the team 
decide about including it in this release. Personally, I don’t care :-) (apart 
from my own ego being able to say « I contributed to making this release 
compatible with FreeBSD »)
