This would, indeed, be nice!

However, after `urpmi xvattr'
(and reading the xvattr man page)

I get:

    [root at cortex root]# xvattr -a XV_BRIGHTNESS -v 24
    Found Xv 2.2
    X Error of failed request:  BadMatch (invalid parameter attributes)
      Major opcode of failed request:  142 (XVideo)
      Minor opcode of failed request:  13 ()
      Serial number of failed request:  11
      Current serial number in output stream:  12

Same error if I leave off the -v 24

I also get:

Finally, I tried re-building the xvattr .rpm from the .src.rpm without
any "measurable difference".  All suggestions appreciated.
