[ydl-gen] Video modes on the PS3

[Rob Nava]

Did you try switching to 'root' before running ps3videomode?  I'm pretty
sure non-root users can't run it.

If you're using a Samsung 940b, you're native resolution is actually 1280 x
1024 (http://www.samsung.com/Products/Monitor/LCD_Digital/LS19HABKBXAA.asp).

Also, if you add 128 to whatever mode you want to run in, you can get the
true resoultion expected.  Normally, the PS3 compensates for the overscan on
Televisions that would make the edges of the video be 'off screen'.

I run in 1080p mode with ps3video 131 (mode 3 + 128 for non-overscan mode).

Try ps3videomode 140 on that 940B (1280 × 1024 with non-overscan mode.)

Also, running ps3videomode from the enlightenment desktop would screw up the
video pretty badly for me.  So try changing the kboot.conf file to offer
different ps3video options.
