Devfs isn't the problem. You can do it as well (if not better) via the existing userspace program.
What we really need are longer device numbers in all file systems, esp. ext2 of course. Everything else is (more or less) taken care of -- glibc already has large device numbers, a new kernel stat() system call version is easy to do, ditto for extending the kernel's idea of dev_t; all the old code should work OK as long as you don't need devices with minor>255.
The real compatibility problem is stuff like "check if /path/to/a and /path/too/to/b point to the same file" -- suppose you want to copy one to the other, a is on 08/01 and b is on 08/101 (i.e. SCSI disk #17), and both have inode 56...
