Booting Mac OS X from CD

When booting from the Tiger install DVD, it would be really nice if Apple could change the startup screen (the gray apple logo on the gray background with a progress spinner) to somehow indicate that a CD/DVD is being booted from.

I was getting a kernel panic on boot the other day, and I had put in the DVD and was holding down the C key (to boot from it), and was still getting the panic. I thought there was a hardware problem, so I proceeded to pull memory, etc. without avail until I realized it was because my keyboard wasn't plugged into the keyboard extension cord I had plugged into the computer (I normally use a monitor switch, so don't often use the keyboard extension cord), so it wasn't getting my message to boot from the DVD.

Any kind of boot-time difference in display for booting from CD would have helped in this case (as I wouldn't have been seeing it, so I would have known it wasn't properly trying to boot from the CD). Back in Mac OS 8/9 days, there was a special desktop pattern that would indicate this state. I'm sure Apple could come up with something more attractive these days, but I'd like to see them to something here.
