You can still access the ROM routines, even using a different bootblock.
This all works:
        InitGraf(&qd->thePort);
        InitFonts();
        OpenPort(&gPort);
        EraseRect(&gPort.portRect);
        TextFont(monaco);
        TextSize(9);
        printk(">> NetBSD BOOT: 32768 k [0.0]\n");
        printk("Boot: [[[sd(0,a)]/netbsd][-adrs]] :- ");
        printk("\n");
        EjectDisk(BootDrive);

But.. only with crtmac.o, and libmac.a (under MacMinix)  Perhaps the
startup code from MacMint might be used, as the MacMinix stuff is copyright
Prentice Hall.
