Nothing happens for "radeontool light off" with radeontool 1.6.0
for my Dell Inspiron 4000. Downgrading to 1.5-5 works.
Running 1.6.0 under strace yields a normal startup, then

Found card 1002:4c46 (30000)
Radeon found. Base control address is b35a1000; base framebuffer address is
b35a1000.
reading RADEON_LVDS_GEN_CNTL (2d0) is 00ff0000
writing RADEON_LVDS_GEN_CNTL (2d0) -> 00ff0000
$ echo $?
0
My card is indeed a 1002:4c46, which is to say an ATI Technologies Inc
Rage Mobility M3 AGP 2x (r128).
Ideas?
Jonathan
