Osx Boot Resolution



I have the following problem:
During bootup, OSX 10.4 uses a low resolution, but switches to my chosen 1024x768 resolution once I log in. When I log back out, the resolution remains 1024x768.

I would like to somehow implement the following hypothetical procedure:

1. Copy my current screen resolution from the per-user configuration.

2. Paste that screen resolution into the boot-time configuration.

3. Watch the beautiful azure blue 1024x768 bootup screen after I reboot.

Please let me know !

Thank you very much for your help !
