If you have no clue what this is all about, click the above links and read a bit about it.
The xperia(kovsky) research information vital to porting the linux kernel is available at htc-linux.org
The kovsky is very similar to raphael, diamond and the other htc phones that are based on the QCT msm7xxxA chip. This is why the raphael/diamond development kernel code from the htc-linux project runs well on it.
Kovsky has its own machine type in the htc-msm-2.6.27 (see link above) branch now.
