From the R15B README:

OTP-9795 == otp erts ==

The driver interface has been changed to enable 64-bit aware
drivers. Most importantly the return types for ErlDrvEntry
callbacks 'call' and 'control' has ben enlarged which require
drivers to be changed or they will cause emulator crashes.
See

Rewrites for 64-bit driver interface in the driver manual.

Due to this driver version management is now mandatory. A
driver that is not written with version management or a
driver that was compiled with the wrong major version will be
not be loaded by the emulator.
