Please get the latest patch in ibm-acpi.sf.net, it should work with the
T510, and report back what works :-)

Might be fixed in the ibm-acpi.sf.net release. Not needed in your thinkpad
anyway, you should use RandR functionality in the X server.

Does it really honestly mutes, or does it just look like it muted?

Your thinkpad doesn't have up/down/level support, so that's expected. The
driver is a bit confused because of the force_load thing :p

Won't work even in force mode in the version you tested. Please re-test
using the release form ibm-acpi.sf.net.

It is unsafe as in "you do idiotic things with it, and it will fry your
thinkpad", therefore the driver requires your explicit permission before it
lets anything in userspace change the fan controller mode.

When it is working, it usually unplugs the WWAN device from the USB bus.

WLAN might stay up but have its radio blocked. Depends on the quality of
the rf-kill Lenovo is using...
