Only with the old BIOS right? The new BIOS provides very limited support for plug-and-play option ROMs. This needs to be indicated in CMOS memory. This morning I made a quick attempt to change the CMOS boot value to 0x04 which would indicate booting from an expansion ROM but that didn't work. There was a patch on qemu-devel recently that might be worth looking at.
