How about MCS (Mellor-Crummey and Scott) locks?
Linux code:
http://oss.software.ibm.com/linux/patches/?patch_id=218
Something supposedly better:

Scott's list of 11 scalable synchronization algorithms:

Scott's collection of papers and so on:

Simply asking Scott might be a wise move. He'd likely know of anything
else that might fit the requirements. That's scott at cs.rochester.edu
