You're going to HAVE to get to a screen resolution of at least 800x600. Bittmapped games are handcrafted, and don't (generally) resize, and definitely don't resize down.
Every notebook I've seen uses the Intel GMA video chip, and that chip can run higher resolutions than the panel can physically display. Try:
right click on desktop / Graphic Properties / Display Settings
That should take you to the Intel display driver panel instead of the normal XP display control panel. If not, try:
right click on desktop / Properties / Settings tab / Advanced button / Intel Graphics Media tab / Graphics Properties button
On mine, which is physically 1024x600, I can use this panel to set it to 1024x768. I believe you will have to pan the screen when you turn this on, though. (Since mine is an Asus Eee PC, I can also use the EeePC Systray utility to switch it to 1024x768 and even to enable "LCD Compress" mode which makes it all fit at once. I'm not sure if you could get that utility from Asus and install it on your Compaq or not -- probably not, as I would consider it a selling advantage to be able to support a very widely used screen resolution)
If you still can't get this to work, instead of looking at the driver settings, look at youf Monitor settings (right click / Properties / Settings tab / Advanced button / Monitor tab). On my Eee, it is configured with a monitor of type "Digital Flat Panel (1024x768)". If your monitor is configured to not allow higher resolutions, that may limit what the driver will allow.
For anybody who cares, 1024x576 is a 16:9 ratio, compared to the 16:10 ratio of 1024x600. I still consider it unacceptable, since 800x600 is the lowest resolution that XP officiially supports, so any display that is limited to 1024x576 is going to have problems with certain XP dialogs anyway. I strongly suspect that, while the marketing reason is 16:9 displays, the actual financial reason is because it lets them use LCD panels that failed QA passes with dead pixels along the bottom, which they can hide behind the panel -- but that's purely cynical speculation on my part.
