I've tried this, the function is handle_15c0. This happens quite late in the boot process, the FreeBSD code that triggers this issue is at:
Is it possible you are running into:

Might be... I'm not familiar with this code at all, but I will try to see if I can figure out what's going on.
If freebsd is using x86emu to interpret the bios, then I'm not surprised it is having problems. In a previous mail, you indicated a freebsd compiled seabios caused crashes under Linux - can you confirm it crashes on non-freebsd guests (ie, linux, windows, dos, etc)?
I've tried booting Ubuntu using the _broken_ SeaBIOS, and it seems to work fine, I can see calls to handle_15c0 succeeding:
(d10) enter handle_15c0: (d10) a=0000c000 b=00000000 c=00000000 d=00000000 ds=1000 es=1000 ss=df80 (d10) si=00000000 di=00000000 bp=00000000 sp=0000f9f6 cs=1000 ip=02fd f=0003
So it seems like the problem is only triggered when booting FreeBSD guests with this specific SeaBIOS build.
Roger.
