That's the video card's fault.  What options do you have checked in
booter 1.8?

Basically, the problem is that the video card generates VBL interrupts,
but the kernel doesn't know what to do with these except on a couple
of old Apple cards.  The interrupts are therefore only enabled when
there is an ethernet card in the machine (all nubus interrupts are on
one wired-OR interrupt line to VIA2/RBV).
