There is a bug in the e2fsprogs port.
The fact that they are getting 0 blocks implies that they are not getting
good results from the disklabel. (Fact: There is none). I looked at the
source code and it seems they don't even try to use the DIOCGMEDIASIZE
ioctl; is there a reason for this?

If you're a programmer, look into it.
If you're not, bug me and I'll do it :-)
