I have exactly the same problem, I have a Droid 1 running 2.2; build FRG22D. I had this problem on 2.1 as well.
In my opinion, I feel that this issue has something to do with:
1) Lack of memory -- too many widgets / apps running at the same time. I do presently use Advanced Task Killer, but there is no effect (no help).
2) Dock mode -- I use a Blackberry holster (belt hip) which has a magnet. The annoying magnet puts the Droid in Dock Mode (rather annoying). When I remove the phone from the holster, I have to manually exit the dock. At which time, the icons are gone for 10-20 seconds.
I have also noticed the icons disappear when opening / closing the keyboard. I have to assume that the issue is simply some type of a memory problem.
Rebooting the device has no effect and should not be required. Android simply needs to address the problem to ensure proper reliability and stability of the device, anything else is unacceptable.

But at least I have my home screen.
