HELP - I'm so close (I think) to getting my Ethernet card talking...

Mac // (8MB/Mode32/no other inits) with a Focus EtherLAN // NuBus card.
> ae0 at nubus0 slot a: Ethernet Card, 16KB memory
> ae0: Ethernet address 00:a0:4b:00:XX:XX (XX = ommitted for security)

What's installed (from "current-981219"):
	/kernel/netbsd.GENERIC-92.tgz
	/security/*
	/sets/*

Mods after boot
------------------------------------------------------------
File "/etc/hosts"
------------------------------
127.0.0.1	localhost	localhost.mydomain.com
10.10.31.10	mymachine	mymachine.mydomain.com
--<EOF>---

File "/etc/resolv.conf" (nameservers are at my ISP-my ISDN routes me there...)
------------------------------
search mydomain.com
nameserver 205.222.222.111
nameserver 205.222.222.4
--<EOF>---

File "/etc/ifconfig.ae0"
------------------------------
inet mymachine netmask 255.255.255.0
--<EOF>---

File "/etc/rc.conf" (excerpts)
------------------------------
hostname="mymachine"
defaultroute="10.10.31.1"	# my ISDN router
domainname="mydomain.com"
--<EOF>---

NOTE:  Crash doesn't happen if I rename "ifconfig.ae0" and "resolv.conf"....
