Dumping the register content of LVDS_GEN_CNTL and LVDS_PLL_CNTL in the
different cases gives the following results:

Old driver (git from 12/06) has the same value in both registers
when booted with lid open and booted with lid closed:
on boot (same value in both cases):

LVDS_GEN_CNTL (02d0)    0x003dffa5
LVDS_PLL_CNTL (02d4)    0x0001128a

...and the was ok.

Current git gives the following:

Boot with lid open:
 - only internal display active
   LVDS_GEN_CNTL (02d0)    0x003dffa5
   LVDS_PLL_CNTL (02d4)    0x0001328a
 - only external display active
   LVDS_GEN_CNTL (02d0)    0x0035ffa6
   LVDS_PLL_CNTL (02d4)    0x0001328a

Boot with lid closed
 - lid closed
   LVDS_GEN_CNTL (02d0)    0x003dffa5
   LVDS_PLL_CNTL (02d4)    0x0001128a
 - lid open
   LVDS_GEN_CNTL (02d0)    0x003dffa5
   LVDS_PLL_CNTL (02d4)    0x0001128a

Unfortunately the obvious solution (executing
radeontool regset LVDS_PLL_CNTL 0x0001328a) does
not work - the internal displays remains dark.
Maybe this is too late when setting this "manually".

Can you give some hint where in the driver the
regset should be placed? Then I will try further.
