I have now fixed the remaining issues.
Comments are welcome.

------------------------------------------------------
Simplify the pccard dhcp handling a lot. There are now
many configurations which have a NIC on board, and
pccard slots. If a dhclient is running on the internal
nic, the user was forced to kill a running dhclient
manually.
If a pccard is included at startup time, /etc/rc.d/dhclient
start does include it into the startup list for dhcp devices.
That means you can you then dhcp on the internal and the
pccard device.
If the card is plugged in later, a running dhclient (working
for the internal interface only) is killed, and restarted,
but with the interface name of the new pccard.
Here is my example config which works really fine now:
ifconfig_sis0="DHCP"
pccard_ifconfig=DHCP
removable_interfaces="an0 wi0"
