Restore visuals Is not broken in 2.0 B11/Hijack,
you have to first force the player into thinking that its visuals are onscreen.
The way to do this is to switch to your favourite visual using the front panel (i.e. not using the remote OR the Sony Stalk if you have one).

That then sets the correct 'bit' in the Flash memory and then the player will resume from that visual everytime you power on again, if you've set the 'restore DC/visuals' in Hijack.
Note: There are 2 options in the Hijack kernel for this and I'd set both.

Until I did this I had the same problem as you did with visuals not displaying even though I told hijack to do so.

There is a post about this somewhere on this BBS in the last few months and no doubt in the FAQ and if its not, then it should be.
