Sun bug 6872917: Xorg not querying /dev/fb when no xorg.conf exists
commit 48ee555833
(OpenSolaris VT support)
broke the autoconfiguration code in xf86AutoConfig.c that uses the
Solaris-specific VIS_GETIDENTIFIER ioctl on a frame buffer device like
/dev/fb by changing xf86Info.consoleFd from /dev/fb to a /dev/vt/*
device.
This fixes it by reworking the code to split the console device
(/dev/vt/*, the vtXX CLI option) from the frame buffer device
(/dev/fb, -dev option) to allow both VT and autoconfig to work.
It also fixes the console device to use /dev/fb when VT's are not
supported instead of throwing a Fatal Error because it can't open
/dev/vt/0.
