No problem.
I just did a build with latest v3, built a 256kb bios, copy it to a directory, run qemu as follows: qemu -serial stdio -L . -kernel linux-2.6.15-bochs/vmlinux -hdc hda -hda hda
and I get video.
I am using the vgabios-cirrus.bin
I'm not specifying the vgabios specifically, but v2 finds the vgabios-cirrus.bin
Option ROMS are run in Phase 6. Mine looks like this:
Phase 6: Initializing devices... Phase 6: Root Device init. Phase 6: PCI: 00:00.0 init. PCI: pci_dev_init Probing for option ROM Phase 6: PCI: 00:01.0 init. Initializing realtime clock.

When I look at yours I see an error: Phase 6: PCI: 00:02.0 init.
PCI: pci_dev_init
Probing for option ROM
ROM address for PCI: 00:02.0 = c0000

PCI ROM Image, Vendor 0846, Device ec89,
Device or Vendor ID mismatch Vendor 0846, Device ec89
see the mismatch? So it will not run the rom. The option rom does not match the hardware .
Good catch.
What vga bios are you using? I hope to wake up more soon and might actually give a useful answer :-)
I don't know where it's getting another VGA bios. I tried removing the other vgabios.bin file from the directory, but I get the same results.
I looked in the pci.ids file, and the Vendor ID is not there, so I'm not sure what the problem is.
