You can mount devfs on another location...

But that's not the solution either.  Every kernel driver should have
#ifdef CONFIG_DEVFS_FS
and then some code to create device nodes at the time it registers it's use 
of the device numbers.
Device drivers that aren't devfs aware are buggy.
/etc is totally wrong, it's only supposed to have config files.  Doing 
otherwise would make Linux as crappy as Solaris.

The best solution to these types of problems would be to make devfs mandatory 
for LVM and then only use the devfs functionality.  Then device numbers stop 
being a problem.
