OK, I tried to boot this puppy on my Mac IIci, and got the following 
error during the grf1 device probe:

grf1 at nubus0unknown OS trap 0xa11a, no trap address available

followed immediately by a panic in mrg_aline_super().

My video card is an E-Machines Futura-SX 24-bit accellerated 
QD-compatible card.
