No idea if this will solve the problem. I had been getting i2c write 
errors on a ov511 camera initialization, fixed with "modprobe i2c-dev" 
which created the devices. In /etc/modprobe.conf there is a line "alias 
char-major-89       i2c-dev", but on the previous kernel it wasn't being 
loaded, on 2.6.24-rc5-git3 it started working again without intervention.
