Well, before all the QQ and "OMG WTF WHITE SCREEN" complaints start popping up all over the place, I've decided to go and host the patcher to fix the white screen glitch on GBAtemp, so all you lazy people don't have to run around the interwebs. The download link is down at my sig, but incase that does change for whatever reason, here it is. Also, a full set of instructions and warnings are in the link, and credits go to whoever made this, but unfortunately, I can't find the original creator of the patch.
