>How-To-Repeat:
Run qemu-system-x86_64 -cdrom FreeBSD-9.0-RELEASE-i386-bootonly.iso
>Fix:
The change that trigger the issue is the following seabios change:

http://git.qemu.org/?p=seabios.git;a=commit;h=4540409d19a4baeec5006d925cfca19f8038a96e

That said according to the seabios developers, the real problem is on the 
FreeBSD kernel side.
