with udev deprecating/conflicting hotplug, I think this issue is solved
anyway. ubuntu ships a /etc/udev/rules.d/85-ifupdown.rules with this
content:

SUBSYSTEM!="net", GOTO="net_end"
# Bring devices up and down only if they're marked auto.
# Use start-stop-daemon so we don't wait on dhcp
ACTION=="add",          RUN+="/sbin/start-stop-daemon --start --background --pidfile /var/run/network/bogus --startas /sbin/ifup -- --allow auto $env{INTERFACE}"
ACTION=="remove",       RUN+="/sbin/start-stop-daemon --start --background --pidfile /var/run/network/bogus --startas /sbin/ifdown -- --allow auto $env{INTERFACE}"
LABEL="net_end"


I don't know what objections Md has to this solution, but this
faciliates hotplugging interfaces massively.

FWIW, I think this bug should be cloned, one for the hotpluging part,
which can be closed, and one for the driver backend autodetection, which
is a more tricky one. But considering that the available wlan drivers
seem to consolidate on wireless extensions, the backend wext should work
on every wlan driver some time, so that this bug will solve itself
somewhen.

Nevertheless, if anyone has a clever Idea, feel free to propose it on
our mailing list. We just focus on other, more important problems right
now.
