CONFIG_NR_CPUS=6 is the culprit; things get pretty far in the attached
log which basically did nothing but change CONFIG_NR_CPUS to 32 in
current bk. I think elftoaout, gcc (well, this is 3.3.3), and so on can
all be ruled out simultaneously for this.

Solaris can talk bidirectionally over the same wire, dhcp config, NIC,
etc. but ethereal and tcpdump see limited outbound traffic and no
upper-level protocol acks etc. out of Linux. There could be something
going on with the hme driver. I'm investigating tricks to get the PROM
to somehow recognize the CD's I cut in the meantime.
