I misreported bootchart 4's time it should have been:
4 - Time 25.01. Boot with disabled readahead.

Further testing shows that ureadahead IS seeing the udev rule's changes even when launched at the mountall stage so my previous comment saying it wasn't is in error. Perhaps what threw me is that ureadahead decides whether it should use hdd or ssd mode by what is in the pack rather than what /sys is currently reporting.
