Typically only syscons cares about having a VGA adapter. I don't see if you have syscons configured or not, but assume you have. I also don't see it mentioned wether you normally use a serial console or a graphical console. So, it's hard to come up with any good hints. My first guess would be: remove syscons (or remove the hint from /boot/device.hints. Make sure you have a suitable alternative for the console. I forgot if promcons could survive multi-user mode, so you may want to have sio(4) or uart(4) lined up as the console. -- Marcel Moolenaar USPA: A-39004 marcel@xcllnt.net
