AFAIK, the only write access udev initscript needs is to create the device 
cache. It is controlled by the DEVCACHE variable in the /etc/default/udev - 
either point it to a read-writeable and mounted partition or disable devcache 
by unsetting the variable (all Zaurus machines do that by default).

I've been meaning for some time now to fix it by moving the devcache handling 
after the checkroot... But since all my machines mount rootfs writeable, it 
hasn't been very critical for me - need to find some spare time actually do it 
properly :)
