No good way that I can think of, other than replacing all calls to 
trellis.device() by trellis.device(theme = col.whitebg()).

A hack is perhaps possible, which involves the global variable lattice.theme, 
which stores the settings. If you have that variable in your global 
environment (as part of your saved workspace, for example) with components 
for all the devices you want to use, lattice will use it. This will work if 
you start devices with x11(), postscript() etc. Unfortunately, any call to 
trellis.device() to start a new device will overwrite this unless retain = 
TRUE is specified. This includes the default invocation when print.trellis is 
called without any device open.
