That one does the trick as well. Thanks, Mark

Failure to load the firmwares on ARUBA isn't considered fatal. However modesetting doesn't quite work in that case. On an HP Pavillion Sleekbook 15 with A4-4335M APU, I end up with a screen full of garbage. Calling evergreen_mc_program() fixes the issue. Diff below is against the OpenBSD codebase, which corresponds to Linux 3.8.13. Signed-off-by: Mark Kettenis <kettenis@openbsd.org>
