Short answer is no, sorry, but thank you for asking.

After the 2.6.20 fiascos we cannot afford more debugging for Linus who needs to
fix his development philosophy.  The last report I can give is 2.6.20.15 in grml
1.0-1 with CONFIG_USB_SUSPEND turned off.

Upper-case -Y doesn't work:  it hangs the PC when issued.

Lower-case -y still behaves as before,

Truecrypt mount/dismount on USB causes IDE drives to re-spin needlessly, too,
independent of shutdown.

Linux doesn't get that there's no reason to spin up without IDE file activity. 
So the kernel has missing and/or corrupted logic.

Therefore I recommend closing the grml bug and sending it upstream to kernel
devs.  Link back here for reference.
