So I *netbooted* the VAXstation 4000 m60... You will notice that the 
on-board network is not recognized. :/

Network appears about every other boot, but I cannot see a clear pattern 
when.
Don't know yet if this is related to the discussed bug.

With network, add between vsbus0 and dz0:

[...]
le0 at vsbus0 csr 0x200e0000 vec 770 ipl 17 maskbit 1 buf 0x0-0xffff
le0: address 08:00:2b:xx:xx:xx
le0: 32 receive buffers, 8 transmit buffers
[...]

else
