seabios 1.7.5 has about 8k free space in fseg.

configure 1.9.1 to keep the same amout space in fseg, so the amout of
disks we are able to handle stays roughly the same.  ahci + scsi are
slightly below the 1.7.5 numbers but stay above the documented limits.
virtio-block numbers are higher than the 1.7.5 numbers.
