libvirt users - Jun 2010 - Are memoryPeek and blockPeek still not supported?

Hi, 
   I just tried x=dom.blockPeek('disk',5,0,buf,0) and it returns
AtrributeError: 'module' object has no attribute
'virDomainBlockPeek'

I found this bug submission from early 09:
https://bugzilla.redhat.com/show_bug.cgi?format=multiple&id=492683

Is that still correct are they not implemented. Or did i screw up the command? 
Thanks,
Steve
