Do you have the hash extension enabled? Without that extension, hashing
algorithms
other than md5/sha1 will not be available.

I face the same problem on PHP 5.2.5 (x64) on my local installation
Windows Vista 64bit.

Description:
------------
This may be an apache bug, though I'll start with putting it down as
php. There is a similar bug: Bug #49469 submitted in 2009 with advice
try the latest snapshot, that was version 5.3.0 and I'm using version
5.3.5 so assuming that advice isn't valid and the bug still exists.
Setting session.hash_function variable in php.ini doesn't change the
value used to generate the hash function.
I've tried sha512, sha1, whirlpool. All of these don't change the hash
delivered to the browser (PHPSESSID) and still the standard md5() hash
is used.
All the hash algos tried are on the system when the output of
hash_algos() is examined.
Specifying 1 does make the system use SHA1 to generate the session
hash.

session.hash_function = sha512
session.hash_bits_per_character = 5
url_rewriter.tags =
"a=href,area=href,frame=src,input=src,form=fakeentry"
Test script:
---------------
session_start()
Expected result:
----------------
sha512 generated PHPSESSID
Actual result:
--------------
md5 generated PHPSESSID
