I checked VGA, but still have no success with TV. Moreover it seems VGA 
has issues with getting available modes. If I do xinit with or without 
xorg.conf it sets improper frequencies. Easiest way I found is 60Hz 
limit ('VertRefresh  40.0 - 60.0') however monitor can 75Hz and console 
works in this mode. Probably I can set proper modeline to get 75Hz but 
driver can not detect it automatically.

Full story below (hope it help clarify what happens):
~2 year ago I bought ATI HD3450 and wasted quite much time before I 
catch that VGA and DIN can not use different CRTCs. Then I bought 
DVI2VGA connector and TV works fine on CRTC#0, DVI on CRTC#1. TV was 
broken after I switch to KMS.

May be TV has the same issue as VGA and I should make proper raw mode 
with --newmode?
