First, Airssl is a user-script, so asking the author would be wise, and BT team probably won't support it. AS for DHCP issues with this script, search the BT4 forums, it has been widely discussed. And I remember a lot of problems with Mac and DHCP. As for the rest, I don't know !
About the AP chipset... I believe the 036H has AP support ! (I can be wrong though, you'd better check )
