I am trying 2.6test4 with the latest patch and some applications
(certainly zapping and tvtime but maybe others) have trouble, because
they don't set the memory type field in the buffer request/query ioctls.
Fortunately, this is trivial to fix, here is a patch for tvtime.
On a vanilla 2.6test4, even these broken applications work well.
Regards,
