This sounds to me like my suspicions where right. Somehow the code to install the boot_ec handlers is called before the context has been created. Both places acpi_scan_init() (which tries to install the handlers) and acpi_ec_dsdt_probe() (which allocates the structure and would create the context) run concurrently but do not protect against this. I tried to reopen the kernel bugzilla but this could only be done by TJ or ykzhao (wrote an email to him). In the meantime I try to think of a way around that.
