I'm trying to install OpenBSD 5.6 amd64 on my 2012 Mac mini (quad-core Intel i7), but USB stops working partway through the boot sequence, as evidenced by my lighted keyboard going dark. Without a working keyboard, I am unable to proceed through the installer.
The keyboard works just fine during installation and use under OpenBSD 5.5 amd64 on this Mac mini. Attempting to boot the 5.6 installer on another Mac mini (dual-core i5) also results in the same issue, so it's not something wonky with this particular machine.
I have tried install56.iso, install56.fs, cd56.iso, and bsd.rd from the release version of 5.6. I have also tried install56.iso from two recent snapshots. None of these work.
Here's the text output on the screen as it boots, videoed and hand-transcribed (there might be typos):

There is some mention of USB and the keyboard as it's booting, but at this point my backlit keyboard is unlit and pressing keys doesn't do anything. No other keyboard I have works. I have tried plugging in the keyboard to all the USB ports on the system, it does not help.
Any ideas what the problem could be? Is there any way to control this system without needing a USB keyboard?
