I've attached a patch that adds a few rules to udev.rules.devfs, making it
look a little more like devfs on my system. (I have the sysfs patches from
2.6.1-rc1-mm2) I added rules for oss, misc, floppy, and input devices. The
oss rules look like trouble with a wildcard at the end of each name, but I'm
not sure how I can make it any better.
Devfs has a bunch of other devices in the floppy directory for floppies
formatted in unusual ways, but I don't see them in udev. Not that I ever used
them, since they're usually automatically detected.
