I installed the latest 2007HE to my flash. I have OS2006 on my mmc. I had the problem you had with no onscreen keyboard. I had to reboot and I think I got it back. I also had a problem with the memory and it shutdown and my Nokia 770 would not boot up at all. I had to remove the batteries and then restart. Boy was I sweating for a bit. I installed seatbelt and changed the swappiness to 20. Everything has been running great since. I am tempted to put it on the mmc but I will wait a bit. I would also go to control panel and click Text input settings and change the input method to Handwriting recognition and see if you can get the handwriting screen up.
