It's not obvious to me that this is the right approach. Other OS'es
support proper VT's on non-primary graphics cards. OpenBSD is such an
OS, although we don't particularly care about multi-seat setups at the
moment and don't actually use the seatWhatever stuff at the moment.
But if this gets committed, please use
if ((flags & HW_SKIP_CONSOLE)) || !(ServerIsNotSeat0())
since the !HW_SKIP_CONSOLE condition is the more important one since
it applies to all platforms. Whereas the ServerIsNotSeat0 check only
applies to Linux setups.
Cheers,
Mark
