the options that are logged by the driver are those passed into
xf86SetFooOption(), provided the option is set. this doesn't necessarily log
all options though, the xf86OptionListReport is especially handy to find
settings where an option is set but ignored by the driver.

synaptics used to have xf86OptionListReport in the driver before I kicked it
out recently, but having this in one place in the server seems a bit more
