The "can't get a DHCP lease" connection issue with an unencrypted access point seems resolved with the 2007-09-04 ipw3945 driver from http://bazaar.launchpad.net/~asac/intellinuxwireless/ipw3945.asac . Also (still) seems fine connecting using WPA (but that might have always worked due to wpa_supplicant not being quite so fast to make connections).
