That 0x19 status code in Association Response would indicate that the AP
rejected association due to the client not supporting Short Slot Time. I
would have expected BCM4306 to support this as a 802.11g card, so I
would guess that SoftMAC is not setting the Short Slot Time flag
correctly. As such, I do not think this issue has anything to do with
wpa_supplicant and this should be reported to SoftMAC maintainers

(though, I would recommend replacing netdev with
linux-wireless at vger.kernel.org and you may even find a SoftMAC specific
mailing list by going to the web site mentioned above).

I believe this issue with SSID length was already resolved with 0.4.9.
In this case, the first issue would likely need to fixing SoftMAC (or
alternatively configuring the AP not to reject STAs based on Short Slot
