When the X server is started (even though SuperProbe correctly detects that card and memory) with acceleration turned on (the "noaccel" option is not supplied), the monitor flickers to change modes, and then the system hangs, not even allowing me to drop to KDB.
The quick fix is to turn acceleration off:
add 'Option "noaccel"' to the Device section of /etc/XF86Config
How-To-Repeat: make sure you are using the Trident 3Dimage985 card (I have 4M on it)
install XFree86-3.3.3 and configure it without 'Option "noaccel"'
startx and watch it hang
This is more of a XFree86 problem than a FreeBSD problem. Please submit it to
