The reason for using the obsolete functions is portability. The same OSS 
driver binaries work both under Solaris 10 and 11 but only if we use the 
obsolete functions. The obsolete ones are defined in all Solaris 
versions (up to NV). The new ones are not defined by Solaris 10 (and 
earlier).

Who knows. My understanding is that these functions have just been renamed.
