As far as QEMU is concerned, it emulates a sun4u machine with VGA
graphics with VESA, which simply cannot work in reality. Thus, I
don't see much point in putting efforts into making that work with
FreeBSD and using QEMU with "-nographic" is the way to go.
Apart from that and as you say, the level of sun4u emulation provided
by QEMU/OpenBIOS generally seems rather incomplete. Actually, the
environment provided by the latter [1] appears to be absurd:
"OpenBIOS/SPARC64 is currently able to boot the following OS/kernels:
* Linux (with virtio drivers)"
WTF? :)
