Well it used to work fine on OMAP+TWL until one of Peter's rework patches, I guess 6b87a91f (haven't really bisected), hope we can find some solution. We have some closed OSS programs that we can't drop, unfortunately. I know userspace OSS emulation solutions exist, but it wouldn't hurt to have more options.
