IIRC older Qemu versions can't handle ROMs of that size. I could be
wrong, though.

Hmm, the qemu changelog (http://bellard.org/qemu/changelog.html) doesn't say
anything about that. I've certainly never seen that problem on 0.9.x. Anyone
run into this?

Thanks,

http://www.coreboot.org/QEMU_Build_Tutorial#Building_or_finding_a_Linux_kern...
says this:
[...]ensuring that the final coreboot image does not exceed QEMU's BIOS
size limit (2MB if qemu-bios-size patch applied, 256KB otherwise).
