Alpha does declare them (e.g. 2.6.0-test2):
#define __NR_pread64                    349
#define __NR_pwrite64                   350

This means you should do something similar to
e.g. sysdeps/unix/sysv/linux/powerpc/powerpc64/sysdep.h
(either exactly what ppc64 does plus your patch below, or
replace pread64/pwrite64 with pread/pwrite and vice versa
and you don't need syscalls.list change).
