I'm pretty certain that if ESX detects that it is running under ESX, it 
disables SVM/VT.  There was a fair bit of noise a few months ago because 
a certain beta version of VMware didn't do this which meant you could no 
longer run ESX nested.  They quickly fixed that.

I'd try disabling vmport and the hypervisor present bit.
