layout without any further kernel side adjustments: Since it is known that a
CRC always is a 32-bit value, simply checking whether the so-far-used 64-bit
value has more than 32 significant bits should suffice: If so, the new layout
is being used (with the symbol name starting at offset 4), else the old one is
in effect (name at offset 8). This ought to be a pretty trivial change to that
code.
Most of the distros can fix that with a dependency on the kernel package
in the absolute worst case, not that I love that idea, but it happens. I
assume for now we are going with detecting the two possibilities because
it doesn't really hurt in any case to have this support.
