modules tests cause -current to crash

[Jeff Rizzo <riz%netbsd.org@localhost>]

I'm currently in the process of getting a machine (g4/400 with 1G RAM) 
up in order to regularly run the ATF test suite on the macppc port... 
but it seems that the 'modules' tests are a convenient way to panic the 
system.  :}

What's the state of module-loading support on macppc?  I see that 
GENERIC is configured as MODULAR, but given that the basic tests don't 
pass...

to see what I mean, try this on a -current system that you don't mind 
crashing:

# cd /usr/tests/modular
# atf-run | atf-report
Tests root: /usr/tests/modules

t_modctl (1/3): 5 test cases
    cmd_load:

*boom*

DDB shows a kernel PGM trap that I'm too lazy to ten-finger copy right 
now in module_do_load.  (incidentally, my usb keyboard doesn't really 
work in DDB - sometimes I can type a character or two before it goes 
dead, but it always goes dead)

For now, my next step is to figure out how to skip the module tests...  ;)
