Make sure dsdt + seabios are in sync.  latest bios.bin + dsdt from qemu
tree isn't going to work.

With qemu/master (4524051c32190c1dc13ec2ccd122fd120dbed736+) you can
simply use 'qemu -L /path/to/seabios/out' and qemu will pick up both
bios.bin and dsdt tables from the seabios build output dir (and
everything it doesn't find there such as vgabios blobs from the default
paths).
