The file is a rom image padded to 64K.  The 70K comes from an elf
header tacked on to the rom image.  (There are probably more efficient
ways to tack on an elf header - but this works fine for now.)

The actual size of the rom before padding is around 45K.  With
coreboot-v3 and lzma compression (tested only under qemu) I get:

start 0xfffc3e80 len 19930 reallen 65536 compression 1 entry 0x000f6b70 loadaddress 0x000f0000
LAR: Compression algorithm #1 (lzma) used

Of course, this is with a bunch of things disabled (eg, no APM) so
these numbers are likely to go up.  However, all in all it is not
