J1 is indeed a group of 8 jumpers. You need to remove the jumper between 
pins 1/2 of J1. However, the kernel *should* print a message (then exit) 
when it starts up if you forget to remove this jumper so I doubt that's 
your problem.

I suspect the real fix will be to write zero (32-bits) to address 
0xfffc0000 of the NVRAM. This location, together with 0xfffc0004, 
specifies the start/length of any RAM present on the VMEbus which is to 
be made available to NetBSD. Writing 0x00000000 to 0xfffc0000 using 
Bug's "mm" command will disable this feature.
