Hi,
as promised yesterday, here is a patch that drops the explicit methods
given in the udev config and implement only one type of rule.

A rule now consists only of a number of keys to match. All known keys
are valid in any combination. The former configs should work with a few
changes:

  o the "<METHOD>, " at the beginning of the line should be removed

  o the result of the externel program is matched with RESULT= instead if ID=
    the PROGRAM= key is only valid if the program exits with zero
    (just exit with nozero in a script if the rule should not match)

  o rules are processed in order they appear in the file, no priority

  o if NAME="" is given, udev is instructed to ignore this device,
    no node will be created


  EXAMPLE:

  # combined BUS, SYSFS and KERNEL
  BUS="usb", KERNEL="video*", SYSFS_model="Creative Labs WebCam*", NAME="test/webcam%n"

  # exec script only for the first ide drive (hda), all other will be skipped
  BUS="ide", KERNEL="hda*", PROGRAM="/home/kay/src/udev.kay/extras/ide-devfs.sh %k %b %n", RESULT="hd*", NAME="%1c", SYMLINK="%2c %3c"


The udev-test.pl and test.block works fine here.
Please adapt your config and give it a try.

thanks,
Kay
