Hi,

http://fanoush.wz.cz/maemo/initfs_flasher.tgz is now updated for OS2008. Seems to work with N800. Not sure about N810 but hopefully it is same.

Booting old 2007 system somehow works. So far I noticed wi-fi doesn't see any APs so you cannot connect (pretty major issue :-) and arrow keys do not work (other keys do). Otherwise it works, tried bluetooth, touchscreen, sound, video. USB may need some tweaking too due to enabled host mode, haven't tried yet.
