This instruction is already obsolete. As I've already noted, IDE core now supports warm plug via sysfs, see Documentation/ide/warm-plug-howto.txt. One can plug and unplug any time, this just won't be automatically noticed by the kernel, so one will need to notify it.
CF insert and remove events are very different from writing some sysfs files. They are handled through a pcmcia_socket abstraction ... and are completely hands-off. Socket events include card insert/removal detection, and socket operations include power on/off and reset. I don't know that "true-IDE" links work through those sockets, though.
That said ... I tried that manual workaround; it didn't work.
So: no, that instruction is far from obsolete.
So, it would only work with real hard disks... sigh. Sorry for disinformation then -- I hoped warm plug could've been helpful for CF.
