I bet ehci-hcd does not need to be unloaded before poweroff; unbinding it should work just as well. Sure, it would be nice to fix this -- but if it's caused by a crappy BIOS then fixing it won't be easy.
Although ehci-hcd claims it should be loaded before ohci-hcd and uhci-hcd, this isn't really necessary. The only reason is to avoid unlikely problems when a high-speed device is first initialized at full speed and then switched over to high speed when ehci-hcd gets going.

Only today I could test that theory and you were right: unbind also solves the problem.
Now we only need some kernel hacker to look into this... (my experience with the kernel mailing list is not too famous).
