I build 4.7.0 with JB patches, and a similar config as before, and the matching wifi driver.. all uploaded to the usual place http://www.zaurus.org.uk/download/toshiba_click_mini_l9w/ uptime before total lockup was about half an hour. no other special patches. if I can find the references to specific patches, or someone can point me to them, I'll give them a go.
