Probably not anything new from Asus. I just recently purchased one, and it's pure UEFI. The newest models have begun removing the options to enable "legacy mode", so you can't run legacy operating systems anymore.
This will probably become more and more common, and after the next couple years it will be extremely hard to find any good laptop that would run openBSD.
Interesting. I want a "developer-class" laptop. Well-built, moderately fast, reliable. The reviews on Amazon for that X240 complain about a crappy trackpad. Wonder if there are other good options.
The trackpad on this series is not the greatest - I'm finding precision not very good. (X230 running Xubuntu 14.04.) There's probably some setting to make it less annoying.
OpenBSD tends to re-engineer things rather than use reference implementations - for example, their ACPI (power management) interface is a ground up implementation, whereas most others are simply copies of Intel's code: http://www.bsdcan.org/2009/schedule/events/131.en.html
It is possible to install OpenBSD on vultr.com by using the custom ISO procedure. I got one last month, and it works great. You can also try using the SSDVPS coupon code to gain $20 of credit (it worked last month, but I can't seem to find if it's still active).
LKM(4) support had mostly been only "compile tested" for years. Practically nothing used it, and at the time of it's removal the ports tree contained a single module.. a firmware flasher for some old Dell servers.
