Q: is VT not already enabled on sony z-series under Linux completely
independent from bios?

Simple test on cpu flag 'vmx' like:

 # begin test
echo; echo -n "  Full-Virtualization is ";\
grep '^flags.*vmx' /proc/cpuinfo || echo -n "not ";\
echo "suported by your CPU"; echo
 # end test

and a working kvm (out of the box) makes me suspect that it does..

The report this link [2] is pointing to is speaking about bios. But one
can eg. completely bypass any bios update by simply installing the
newest Linux Processor Microcode Data File from Intel [1]:

sudo apt-get install intel-microcode microcode.ctl

But even without the newest microcode installed I have got full
virtualisation support on my VGN-Z21MN (ubuntu-jaunty and -karmic).
Without any changes to the bios.

Or did I just misunderstood everything?
