This is on NetBSD/i386 1.4.1

When the system boots into multiuser the screen turns blank (black) and
the monitor powers down (suspend) after this line is printed on the
console:

setting tty flags

What could be causing this? I thought graphics adapthers didn't use
IRQs, but is that what's happening here? I.e. something (the NE2000?)
grabbing the Mach64's IRQ?

I've messed around with the BIOS settings, turning off PnP-OS and
marking the appropriate IRQs as being used by ISA and so on, to no
avail.

The system continues to boot into multiuser and I can log in via the
network, so all is not lost. Would be nice to have a working console
though... ;-)
