That was because we didn't know if the LBA support code would work
fine in all environments, so we decided not to define the macro until
0.6.
Anyway, I don't think the fallback is good, and get_diskinfo should
make sure that LBA read/write is really functional instead. I'll do a
different fix for it.

No. CHS values returned by LBA are all meaningless.
