It has been added into -mm ... This is all Johannes can do right now.  
After living in -mm for a bit, it is up to Andrew Morton to forward the 
patch to Linus.  As of right now, you must grab from cvs for this 
driver.  In a few days (or sooner), Andrew will release 2.6.13-rc1-mm1 
.... The patch will be included in that release... See below:
