I think this basically means that there's something about your hardware which isn't supported by the sdhc/sdmmc subsystem in OpenBSD, but (though I'm no expert in the area) it feels like it probably doesn't give enough information to point out a direction to look next. I'd suggest installing to a USB drive instead. After booting that, collect information from sendbug(1) to make a bug report (often simplest done by running "sendbug -P > /tmp/sendbug.txt" and then sending the file from a normal email client to b...@openbsd.org with a description of what happens - please run sendbug as root to get more information). Not sure how familiar you are with OpenBSD, but if you can get it installed as above and build a kernel with SDMMC_DEBUG defined, it's likely that would get information that would have a higher chance of helping people who know more about that area to track it down..
