bsd broadcom netxtreme 57xx compatibility

[Niklas Rosencrantz <niklasro@xxxxxxxxx>]

Greetings with thanks to all responsible for a very desirable bsd. I'm
a python/java/C user and scripter looking to setup a 2nd dragonfly
bsd for basic usage where the first installation went perfectly,
must now for a 2nd slightly different hw disable ACPI to complete boot
since otherwise it stops at paralell port, which I don't have,
detection.

The network my rationale is to get online is offline, where same config with another laptop's slightly
different hardware same brand works fine (though leaving learning to do such as X config for nonroot and learning app adding and path updating)
and this computer, 2nd in a small network where ifconfig outputs
bge0: flags=....<UP,BROADCAST,RUNNING,SIMPLEX,MULTICAST> mtu 1500
options=1b<RXCSUM,TXCSUM,VLAN_MTU,VLAN_HWTAGGING>
ether [ip6 address]
media:Ethernet autoselect (100baseT <full-duplex>)
status:active

After /sbin/dhclient bge0 it gets no link...sleeping and active turns
to status: no carrier

+ how to install python for everybody and X for non-root usage which
probably is learning to adjust my path, since I locate the python.

please inform if informative.
best regards
H Niklas R
