According to a redhat xorg maintainer:
"The use of the "void" input driver in xpra is obsolete. This driver existed to provide empty input devices back when the server required at least one pair of input devices to exist. That hasn't been true since server 1.6 (in 2007).
The only use of it seems to be in the xorg.conf where it can be safely removed i.e. both InputDevice? sections and the references in the ServerLayout?. The server will initialize a default device for both."

Done in r9165 for trunk, due to be released real-soon-now(tm).
Unfortunately, this won't go into the v0.14.x branch because we still support centos5, which ships with Xorg version 1.1
