 In fact, this problem is described in UPDATING:
         The TTY subsystem of the kernel has been replaced by a new      
         implementation, which provides better scalability and an        
         improved driver model. Most common drivers have been migrated to
         the new TTY subsystem, while others have not. The following     
         drivers have not yet been ported to the new TTY layer:          
                 cy, digi, rc, rp, sio                                   
                 ubser, ucycom                                           
         Line disciplines:                                               
                 ng_h4, ng_tty, ppp, sl, snp                             
         Adding these drivers to your kernel configuration file shall
         cause compilation to fail.
 But "Hardware Notes" has all this devices listed as supported.
 Probably, this devices (except for ng_tty, which was updated in
 20081225) must be marked as temporary unsupported until
 their drivers were fixed.
