Hardie can be direct applied to blocks.  This is according to 
Hardie's own instructions.  The structural issues are pretty basic. 
As part of this application Hardie also recommends (and this is more 
than a good idea, but a necessity) applying a water resistive coating 
on the blocks.  In other words, painting the block (or coating the 
block) with a liquid closed (semi vapor open) coating.

I prefer to install the Hardie on furring, not for structural reasons 
- more for water control reasons.  But it is a preference, not a 
requirement.
