video (crt) status inconsistency

Hi,
I attached a VGA monitor to my ThinkPad R50e. Xrandr seems to work well
under Linux 2.6.38-rc6, the Intel DRM driver does what I want, for
example:
$ xrandr
Screen 0: minimum 320 x 200, current 1920 x 1848, maximum 2048 x 2048
LVDS1 connected 1024x768+0+1080 (normal left inverted right x axis y axis) 0mm x 0mm
1024x768 60.0*+ 85.0 75.0 70.1 60.0* 43.5
[...]
VGA1 connected 1920x1080+0+0 (normal left inverted right x axis y axis) 477mm x 268mm
1920x1080 60.0*+
[...]
at the same time, however, /proc/acpi/ibm/video indicates that only the
lcd (LVDS1) output is active:
$ cat /proc/acpi/ibm/video
status: supported
lcd: enabled
crt: disabled
dvi: disabled
auto: disabled
commands: lcd_enable, lcd_disable
commands: crt_enable, crt_disable
commands: dvi_enable, dvi_disable
commands: auto_enable, auto_disable
commands: video_switch, expand_toggle
Or maybe I misunderstand something, but definitely both outputs are
enabled and actively used under X.
Clarifications on the matter welcome; my aim is to configure the video
switch hotkey (Fn+F7) properly.
Thanks,
Feri.
