So... I disconnected CMOS battery and now I have two different blinking patterns. I googled a bit, and it seems it is symptom of some PROM failing. So likely Linux had nothing to do with this, and sorry for the noise. I have X230 now. Suspend/resume works without bricking it with (different?) 6.12-rc0. I hate the keyboard, and X230 came with bad battery and won't charge X220's battery (bad Lenovo!!), so I got another X220. If this one dies with blinking LED, I'll certainly let the world know.
