Should work ok. CF cards behave exactly like IDE disks. The adaptor=20
(CF/mini-IDE) is available for $3 or so on eBay. Should fit into=20
ultrabay adaptor just fine.

I think you're in trouble. The suspend scripts are designed to rmmod the=20
usb devices. This means you *have* to unmount the stick. Therefore, you=20
*must* close the files which are on it before unmounting.

Do you really need suspend to RAM?  Suspend to disk would probably work o=
k.

I'm afraid I'm not sufficiently expert to advise on the answer, but I=20
*think* it isn't possible.
