Single Application Operating System

I am going to start an ambitious project for my senior year of college. Just as the title says:
I want to write a single application operating system that is dedicated to running only one application and none other. I need to build a bare bones UNIX operating system that will use provided binary files to run an open source music production application.
I plan on working on this over the next year with my professors and I will continue to develop after I graduate.
I am open to any and all languages. What do you think would work best?

Why:
I have older laptops that are obsolete (512 MB RAM with 1.0 GB processors) and I would like to dedicate them to running only one application. These laptops have a hard time just running Windows XP which leaves no room for running ANY applications. I dont want all the useless user friendly mess that comes with todays operating systems. Why else? Because this seems hard, so why not?Smilie
How:
I want to work directly with or right above the assembly language and keep any high level programming to a minimum.Smilie I need the computer to boot straight into the application, ie: I turn it on and it automatically starts the one application and dedicates the entire computer to running it.
I'm not going to come straight out with my idea on how to do this, but I would like to see what all the wizards out there think of this.

USB 2.0 MUST WORK Smiliebut is not important at this stage.

dxpower(8)						      System Manager's Manual							dxpower(8)

NAME
dxpower - controls energy saving features on systems that can be power managed SYNOPSIS
/usr/bin/X11/dxpower DESCRIPTION
The Power Manager application, dxpower, is used to maintain and manage the power management features on computers and peripherals that can be power managed. Power Manager lets you place monitors in three power saving modes: Standby, Suspend, or Off and lets you selectively spin down inactive disks to reduce power consumption. You also can specify when you want power management features to be active: always, never, or only at a specific time of day. Privileged (root) users have the capability to set system wide power management values. Non-privileged users set power management values on their monitors for the current log in session. The Power Manager application can be invoked from: The CDE Application Manager Application Group: System_Admin System Admin Subgroup: Dai- lyAdmin If you are not using CDE, start Power Manager from the command line: # /usr/bin/X11/dxpower For more information about how to use the Power Manager application, start the application and click on the Help button. An alternative to using the Power Manager application is to set and control power management attributes from the command line by using the sysconfig command. Refer to System Administration for more information about setting and controlling power management from the command line. SEE ALSO
Commands: sysconfig(8) System Administration dxpower(8)
