Disabling echi driver in UKC does the trick. OpenBSD is fully functional on Wyse C90LE.
I want to warn people about one thing. The Thin client in question comes with Chrome video card. It looks like Open Chrome driver doesn't support the particular video chip-set. I was running X on VESA driver which is obviously not desirable. I am not sure if there is bug in Open Chrome driver or just chip-set (I think it was 11 when I looked at xorg.log). I sent dmesg to dmesg AT openbsd and I sent one to misc but I think MARK's server bounced me as a spam since it was sent from dynamic IP without reverse DNS. If anybody needs any information about this do not hesitate to send me a private e-mail. Predrag
