The script makes disk images (files that contain both a disk partition and a partition table. If you use a .ext2 file gem5 expects it to just be a ext2 disk image without the partition table. You'll want the prior not the latter and to name it with a .img extension.
That will use a a compact flash controller in the system instead of mapping the disk into flat memory.
