xrandr with both monitors

i am having problems with dual dvi monitors, no matter which one is connected
to first port stays blank
it seems xrandr is working, i can expand display to blanked monitor, i can open
windows on it, but it won't come out of standby

here is a snippet from Xorg.0.log
(II) RADEON(0): Port0:
  XRANDR name: DVI-1
  Connector: DVI-I
  CRT1: INTERNAL_KLDSCP_DAC1
  DFP1: INTERNAL_UNIPHY
  DDC reg: 0x7e40
(II) RADEON(0): Port1:
  XRANDR name: DVI-0
  Connector: DVI-I
  CRT2: INTERNAL_KLDSCP_DAC2
  DFP2: INTERNAL_KLDSCP_LVTMA
  DDC reg: 0x7e50


Port0 is always blank, Port1 works fine

i use driver 6.12.4. xorg-server 1.6.3, kernel 2.6.32.7, no KMS
my card is
01:00.0 VGA compatible controller: ATI Technologies Inc Mobility Radeon HD 3470
