I had to compile kernel and xorg module and edit xorg.conf.
Works almost perfectly.
X server launches, sets both displays to work and has :0.0 and :0.1 displays.
Xinerama does not work. Netwalker just freezes.
It needs to restart X server to connect/disconnect adapter.
When plugged I can achieve about 20-70mb/sec transfer to its memory with simple dd command.
I got it from local supplier for about 60$ or 50EUR.
It works under windooze too
If any one interested I can post some commands needed to compile needed modules.
