It's been a while, but I remember that a Sun 2/120 could only have 8MB
if you removed the framebuffer and used the serial console, because the
framebuffer starts at 7MB.  From SUN2-MULTIBUS:

bwtwo0 at obmem0 addr 0x700000 ipl 4: tme/machine/sun2/bwtwo type multibus
zs1 at obmem0 addr 0x780000 ipl 6: tme/machine/sun2/zs

I never tested TME with the 8MB configuration, but there's a decent
chance that it will work.
