The latest start.elf from the firmware git repo (commit dated Thu May 31 13:58:04 2012 +0100) put my hdmi TV in 640x480 mode! I git reset it to the previous version and the TV resolution went back to 1920x1080 @60Hz. Not sure if this exposes a bug in my TV or the latest start.elf : )

Can you show contents of your config.txt and post your EDID.
/opt/vc/bin/tvservice -d edid.dat

Can you post result of
/opt/vc/bin/vcgencmd version

Can you attach the actual binary edid file here (using "upload attachment")
