I've found how to make this DVD work. It refused to process PACKET 
command until I have explicitly set it's PATA-legacy transfer mode to 
the maximal supported.

%camcontrol devlist
<ST3500410AS CC34>                 at scbus0 target 0 lun 0 (pass0,ada0)
<MATSHITA DVD-ROM UJDA780 1.50>    at scbus2 target 0 lun 0 (cd0,pass1)

Patch committed to P4.
