I have the same bad hashrate with vertminer 0.5.4pre and vertminer 0.5.3...

I can see a link on github for cgminer CPU and GPU miner for vertcoin https://github.com/Bufius but I can't compile it... and there is no ADL_SDK like every other version of cgminer I saw...

And another thing, when I try to compile vertminer with ubuntu 64bits.... I can't do it with your ./buildit.sh  
I have to tape ./autogen.sh before ....
I will post screenshots this evening...

I have another rig with Xubuntu and my 7970 on it is pulling 330kh/s
