Is the KVM thing a known issue?
Yes, it has been discussed, at least among beta testers and developers, probably also elsewhere.
I have the same problem (on my X5000/40), and for me a separate keyboard/mouse (not to mention another monitor) is currently not a solution due to lack of desk space.
Even worse, I have a menu in UBoot (or rather AmigaBoot, I guess) to select between my various OS4 installations (being a beta tester, I have both a "normal" public state installation and a beta one), and the selection has to be done by means of the keyboard, which was not possible while using the KVM.
Fortunately I have found a solution (or workaround).
If you switch your KVM switch to some other connected machine, turn on the X5000 and wait for about 22 seconds, then switch to the X5000, you should be able to use the keyboard, both within UBoot and within OS4. The same procedure also applies when resetting, i.e. right after reset, switch to another machine and wait those 22 seconds before switching back. At least that's what works for me here.
When switching back, you should be at or a few seconds before the point where the boing ball starts spinning and shooting.
I'm guessing there is something in the various stages of USB initialization in UBoot resp. the OS4 USB subsystem which gets confused if UBoot has "seen" the keyboard too early in the process. But if and when this has a change of being changed, I can't guess. Most users seem not to use a KVM switch ...
