That's true, thanks.

Because of problems with the switch to the right xorg.conf, I decided to
see what happens when a switch-x-to.conf script is loading.
At the beginning of the script, I added these lines:

modinfo $mod >/tmp/module.test
cat /sys/devices/platform/sony-laptop/speed_stamina >/tmp/switch.test

Then I saw that the sony-laptop module is loaded, but the second command
return an empty string, and as a result - xorg.conf is always points to
default (INTEL) config. However, once the system has booted, the same
command returns the correct status of the switch. Perhaps the reason is
the settings of my computer. I use VAIO VGN-Z21MRN, BIOS is R2168M3 with
unlocked "advanced settings".
The only difference from the standard BIOS settings, that option "VGA
Switching" is set to "static". Ie I do not need to use "acpi_osi =!
Windows 2006" hack, because system is started by default in this mode.
However, in theory, this should not affect the switch.

In any case, you're right that the string "grep -qs
speed /sys/devices/platform/sony-laptop/speed_stamina &&" can be removed
from the script, and this solve my problem.
