Once I fixed another bug with de(4) due to ru@'s recent changes I wasn't able
to reproduce an alignment trap with de(4) on my alpha, so although I have a
patch for de(4) I can't test it. How are you triggering the alignment fault?
Do you have something other than 'ifconfig_dc0="DHCP"' in /etc/rc.conf?
