Johan,

The LC-475 and Performa-475/476 probably won't work correctly with the 
current MRG routines in NetBSD.  They attempt to use the same ROM Vector 
Table as the Quadra 605, but have a different address for the 
ADBReInit_JTBL (patches in ROM).  This will probably cause the system to 
fail during ADB initialization.  However, since they have a unique 
Gestalt ID not currently used by any other supported system, all that 
needs to happen is for someone to put in a new ROM Vector Table entry and 
re-build the Kernel.  I'd be happy to do this, but my 68K Mac is still 
off-site.  Maybe someone else on the mailing list can help by building a 
Kernel you can test with.

Unfortunately you have another problem on your system that will prevent 
you from running stock NetBSD, and that's your changed motherboard.  As 
you have said MacOS no longer recognizes your Mac and that's because it 
has no known Gestalt ID value.  This is what NetBSD uses to index into 
it's tables of known ROM vectors in the MRG code.  You could use the 
value of zero as an index, but that would take a custom Kernel, and I 
doubt that those changes would ever be introduced into the sources since 
they'd only support your configuration.

Hope this helps, and good luck.
