A few more details on this issue, after some further experimentation. The Caps Lock key always works fine at the console; the problem I reported only affects X.
My computer has a single USB keyboard (there are no PS/2 ports). If I use "disable pckbd", then the keyboard continues to work fine at the console, and the Caps Lock problem is resolved under X. If I use "disable ukbd", then the keyboard does not work at all at the console. (I couldn't run "startx", so I didn't bother to test X.) To be able to use my keyboard for GRUB and boot(8), I have to enable "USB Legacy" in my BIOS settings. If I turn that off, the ehci BIOS hand off timeout goes away, but both pckbd and ukbd still attach by default (expected?), and the situation seems otherwise unchanged. If I boot into Linux, I see a similar warning in its dmesg logs about a possible BIOS bug because of the failed EHCI USB handoffs. I'm running the latest BIOS revision; I tried upgrading it to see if it would fix the ehci(4) warning under OpenBSD, but it had no apparent effect. (Revert r1.16 of ehci_pci.c had no effect either.) As far as I can tell, using "disable pckbd" is a sufficient workaround to the problem. However, seeing as the console is able to handle having both pckbd0 and ukbd0 without Caps Lock problems, I would expect X to be able to as well.
