Indeed.

The only way I know is to lower the interface MTU to a value below 1280,
which is the minimum MTU for IPv6. On older kernels, you could restore
the interface MTU to its default value afterwards, but this has been
"fixed" in newer kernels (2.6.16.x with x>=59, 2.6.22.y with y>=15,
2.6.23.z with z>=10, and 2.6.24), so IPv6 will bind to the interface
again as soon as its MTU is changed to a value above or equal to 1280.
