For the record - it is not (directly) udev bug; it is a problem of resuming 
from STR - hdc loses its "position":

{pts/1}% LC_ALL=C ll /sys/bus/ide/devices
total 0
lrwxrwxrwx  1 root root 0 Mar 24 19:21 0.0 
- -> ../../../devices/pci0000:00/0000:00:04.0/ide0/0.0/
lrwxrwxrwx  1 root root 0 Mar 24 19:21 1.0 -> ../../../devices/ide1/1.0/

here first channel is OK, second one is hdc and parent is forgotten. 
Apparently it is something introduced in 2.6.16.
