No. But Xen as delivered == hypervisor + tools.

It does the following:
- Search in /sys/**/evtchn for the device number, this fails.
- Compares the existing /dev/xen/evtchn with the error and unlinks it.
- Tries to mknod it again with the error value, this fails.

To possibilities:
- Fix the error detection in this crude device creation code.
- Rip it out and always rely on the system to provide the devices.
For Debian I already decided to use the later one.
