I LOVE those icons. Been using them for months now and forgot where I found them. Gonna +fav them now.
I also didn't even notice that there's an icon for Ubuntu included. Since i plan to install Ubuntu on my Mac this is just awesome. Now I have a great icon for each of my partitions (Mac, Windows and Ubuntu!)
I know how to do a logon screen. Think that's what you're thinking about. I'm talking about when the computer first starts, you hit F11 or F12 and you can select where to boot from: hard disk, cd drive, usb drive, and if you have a partitions on the hard disk, which partition.
I'm saying it'd be nice if it could instead read the operating systems available and display those icons so if I have Ubuntu on a CD and XP on the hard disk, it would show Ubuntu and XP icons. There's no GUI for that as far as I know.
