I configured bootpd to be more verbose and put more information to system
logs. In first configuration (HW address showed by arp) I saw that bootpd
cannot find 00:a0:40:1f:5c:11 in /etc/bootptab. Okey I rem-ed old config
and inserted address reported by NetBSD. Now server successfully replied
to request. But NetBSD still generates the same error.
I suppose that kernel determines HW address of the machine incorrectly and
sends BOOTP packets with wrong address. Server replied to that address but
network card do not receive these packets because it have different 
address.
I think the problem is on NetBSD kernel side and should be fixed. People
who have sonic ethernet board please look at kernel messages and compare
addresses reported by kernel and arp (ping machine and see arp table).
