XDMCP/Gnome login banner formatting

["Waldher, Travis R" <Travis R Waldher boeing com>]

Is there a how to page out there?  Right now it scrolls across both of
my screens at 1600x1200, and keeps going for another 10 or so screens if
they existed.

Would like to be able to change the font size, fix the login banner/uid
splashscreen size.  And would be really spiffy if I could add a logo.

Thanks,
Travis
