GB vs. MB

I like the disk size message in sd.c but since 1MB == 1024*1024 == 2^20,
why is 1GB == 1000MB == 1000* 2^20 and not 1GB == 1024MB == 2^30 ?

I'd really like to see "real" GBs as 2^30 (which would be more consistent
but just the opposite from what all the disk vendors think a GB is
(or should be ;-))
