    Hi Keith,

    Whats the major and minor device for the bt848 device on BSDI?

The way major device numbers are assigned under BSDI is by
editing /sys/i386/conf/ioconf.c.i386, editing the 
array struct devsw *devsw and essentially putting a pointer
to "btkr".  So, the major device on my system may not be
the same as the one on yours . . .

Here was the tail end of my array looks like:
        %DEVSW(tun),            /* 45 = Tunnel Network Interface */
        NULL,                   /* 46 = (unused) */
        NULL,                   /* 47 = (unused) */
        %DEVSW(meteor),         /* 48 = Matrox Meteor Video capture */
        %DEVSW(bktr),           /* 49 = Brooktree video capture */ 
        %DEVSW(apm),            /* 50 = APM Interface module */ 
        %DEVSW(cs),             /* 51 = PCMCIA CS Interface module */
        %DEVSW(fvc),            /* 52 = Focus Video Capture */
        %DEVSW(mc),             /* 53 = PCMCIA SRAM Drive */  
};
