My machine has 3.5GB RAM.
NetBSD won't like that much ram.  Make sure that at most 2GB is made available.

I've removed 2GB and it still hangs.

I've digged a little bit further, and it crashes in 
when it does the first assignment to rp[0]. rp is 0xa00a8004 and ri->ri_bits is 

I assume ri->ri_bits should point to the frame buffer. How do I check if this 
address is correct?
Sounds like a mapping for the framebuffer is missing from the kernel pmap

Could be. I didn't find where the frame buffer is mapped (but I didn't search 
too hard), so
I just disabled the function by letting it return without doing something.

Now it hangs in sys/arch/powerpc/oea/pmap.c, line 3412, where it executes the 

        __asm volatile ("mtsrin %0,%1"
                      :: "r"(KERNELN_SEGMENT(i)|SR_PRKEY), "r"(i << 

In case it's relevant, I didn't mention that this is a 2-processor machine.
I've installed Linux on it and here's the output of /proc/cpuinfo:
