Except that when the disk has been shut down with hdparm -Y, it needs a
reset and that will only come after quite some number of retries ans
timeouts. Not for the faint of heart :-)

Let me know when you have some code to test. I can test with CD-ROM and
Zip in the media bay as well BTW. Are your current changes in Paul's
stable tree or in the bk stable only? Six rsync trees is a bit much for me
to manage :-)

XFree86 related PCI resource diff follows separate.
