It isn't in the posix module, but you can use it with ctypes like this
>>> from ctypes import *
>>> libc = CDLL("libc.so.6")
>>> libc.readahead
<_FuncPtr object at 0xb7de9714>
>>> f=open("z","rb")
>>> f.fileno()
3
>>> libc.readahead(f.fileno(), 0, 0x1000000)
0
>>>
(That example could do with more ctypes magic to set the types and the
return type of readahead...)
