Are you sure it's 0?  Here's the only fragment of code with 
"Unsupported keyboard type":

        if (sysKbPriv.type < 0 || sysKbPriv.type > KB_SUN4
            || sunKeySyms[sysKbPriv.type].map == NULL)
            FatalError("Unsupported keyboard type %d\n",
            sysKbPriv.type);

And you can clearly see that 0 is legal.  The FatalError call eventually
calls abort(), so you're probably getting a core dump too.

Are you sure it isn't -1?  If so I used to see this all the time running 
xdm.  Sun's keyboard and/or kbd driver takes almost half a second to 
"settle down" and return the correct keyboard type after a mode set.
xdm was starting a new server faster than the keyboard could reset.

It is admittedly a kludge, but adding a "sleep(1);" after line 153 of 
sunKbd.c makes the problem go away.

Another, sort of unrelated, but related item, are the lines:

#ifndef (i386) 
#define TYPE4KEYBOARDOVERRIDE 

around line 142 of sunKbd.c.  As of SunOS 4.1 this is no longer correct, 
and at least one way to make it right is to change them as follows:

#if !defined(i386) && OSMajorVersion == 4 && OSMinorVersion == 0
#define TYPE4KEYBOARDOVERRIDE
#endif
