It's /sys/kernel/debug/vgaswitcheroo/switch

But you don't seem to have vgaswitcheroo there either.  Can you
pastebin your dmesg, and maybe your DSDT?  To get the DSDT do:

$ sudo cat /sys/firmware/acpi/tables/DSDT > /tmp/DSDT
$ sudo iasl -d /tmp/DSDT

And pastebin or attach the resulting /tmp/DSDT.dsl.  Thanks,
