For those that remember the details or want a hint: the 8500 roms
want you to say "/onetbsd" instead of just "onetbsd" for the boot
file, either as the second arg to the boot command, or as the nvram
variable boot-file.  I have no idea why "netbsd" works either with
or without the leading slash, but it does.  (Thanks, Allen!)

So the answer appears to be "no".  This kernel was built from
sources pulled on March 27.  It happens for both the GENERIC kernel,
and my custom kernel.  I could really use a little help with this,
since I need "options MROUTING" and the 1.5ZA GENERIC snapshot
doesn't have that in it.  (The GENERIC kernel from that snapshot
is the only one I've been able to boot.)

That's the next thing I'll be trying, but the boot blocks were installed
from the ZA snapshot, so I'm not to sure it will help a lot...
