Using qemu 1.4.0:

Results in:

Any ideas? Can somebody reproduce that?
To get the FreeBSD VM boot use the console, enter the boot loader, then: # set hint.atkbd.0.disabled="1" # boot
But that disables the keyboard.
I was actually digging about that problem. It is indeed present in version 1.4.0, but is fixed in the current git master. The problem is actually not directly in QEMU but in seabios, the update to version 1.7.2.1 commit 5c75fb10) fixes the issue. Maybe it is worth cherry-picking it into stable-1.4 (hence the Cc:). In the meantime using bios.bin from master with QEMU version 1.4.0 should also fix the issue.
What is strange is the seabios commit fixing the issue:

build: Don't require $(OUT) to be a sub-directory of the main directory.
Remove references to "../" and "out/" from the build so that "make OUT=/a/b/c/" will work.

Maybe Kevin has an explanation?
