I have seen that you are working on kernel 2.6.33-rc8, I was going to test it but your warning about data corruption scares me.

I have Fedora 14(rawhide) running with coLinux kernel right now, kmstuned servide is not working properly (maybe fedora rawhide related) but udev has never worked for me on colinux from fedora 7 through 14 and I have had to manually edit /etc/rc.sysinit (currently line 316 for those who read this) every upgrade to comment it out. 

I have read that udev is working on colinux kernel 2.6.33-rc8 and I would like to make the jump, do you think it is ready?
