My PS/2 KVM shows the same problem. Booting without startup-sequence.
So I added some debug-output and found out that my KVM is indeed the problem since it sends mouse-data that is not correct.
Bootmenu gets data that shows that the middle-mouse button is pressed while it is not because the KVM sends some junk due to an apparently not or not correctly implemented PS/2 command.
So I changed that command to an alternative method of getting the button-status and then ran into the problem that the KVM at first identifies itself as supporting four-byte protocoll and a couple of seconds later falls back to three-byte protocoll.
I do not have the slightest idea why it works with W$N. Maybe the W$N driver already includes quite some workarounds for crappy KVMs like that.
I am using a dedicated mouse for my A1 now.
Since the SAM440 does only have USB I tried a PS/2 to USB converter with both mouse and keyboard. Well, it does not work at all with my KVM.

For reason I am not completely sure of, my StarTech KVM has started misbehaving (as it sometimes used to) where a soft-reboot of OS4 would loose my USB keyboard & mouse (and the Computer indicator light on the KVM stays flashing when this happens).
As this had happened after taking my Sam440 away (I left the KVM at home), and some additional cables accidentally coming unplugged from my KVM, I thought it must have something to do with how the KVM was plugged in.
