played with this some late last night. I now have the Connect Plus working in pdaXrom at the same level as on OZ 3.5.3 - you can run wifi or IDE, but not both at the same time. it looks like some arbitration is needed in the drivers when running both in parallel. will continue to dig if/when time permits - it would be great to enable the flash at the same time.
FWIW, I built the 0.3.7 hostap drivers and utils against the latest pdaXrom kernel. I bring up wifi in /etc/hotplug/net.agent (added a new case for wlan0) by downloading the primary and secondary firmware to the card via the prism2_srec util. it seems that these cards need rev "M" Prism firmware, for which there appears to be no flash-based version available...so I'm using the Prism 1.8.3 f/w for now.
