These magic numbers were gleaned from
http://www.raspberrypi.org/forums/viewtopic.php?f=38&t=79330
config.txt is documented at
http://elinux.org/RPi_config.txt
Not sure how complete it is as they add more stuff for new
firmware capabilities etc. hdmi_mode=87 is brand new and not
yet in the above document. Somre more details at
http://www.raspberrypi.org/forums/viewtopic.php?t=5851
There are two commands under Raspbian, tvservice and
edidparser. Together they can be used to dump out what a
display returns in terms of the modes it supports etc.

config_hdmi_boost=4
It boosts the HDMI signal strength. Normal signal strength
may not be enough if the hdmi cable is long.
