I ran into this problem while setting up preDR3 on a G3-266 tower with
AppleVision 17" monitor. Due to the way the AppleVision monitor works, the
system would boot with 640x480 resolution and then (in the MacOS) switch
resolutions only after the AppleVision extension had loaded. I tried switching
the extension loading sequence but to no avail.
The solution:
I then unplugged the keyboard and mouse from the AppleVision monitor base,
(instead plugging them into the back of the computer), and disconnected the ADB
connector twinned with the monitor cable. I then rebooted into MacOS and found
that I had lost all of my monitors and sound prefs. I reset these prefs via the
Monitors&Sound control panel to what I wanted and then restarted. On restart
there was a brief period at 640x480 but then the monitor switched immediately to
the set resolution and presented me with the MkLinux booter. When I selected
MkLinux my term was at the res set previously in the MacOS.
In summary:
Disconnect the ADB cable from the AppleVision monitor, and use the built-in port
on the computer instead.
