Wow, it works! I have spent only two days to find this thread and another five hours to fix it.
Someone really need to make this thread sticky.
Here's another edid file for Satellite 2410 with Geforce 2 420 Go (note that this is for Geforce 2, not Geforce 4!).
Just download the file and rename it to 2410edid.bin. (this is NOT an actual zipped file!)
