After finding the missing bit poweroff works now.
I cleaned up the patch and moved most of the dsdt.dsl and acpi_tables.c into the southbrige/northbridge directory. Updated patch should fix abuild error and incorporates suggestions on irc by uwe (thanks for the comments). Thanks to Idwer Vollering <vidwer@gmail.com> for the original patch. Tested: Linux (poweroff, powerbutton event) XP (poweroff, powerbutton event) Abuild-tested Signed-off-by: Tobias Diedrich <ranma+coreboot@tdiedrich.de> Acked-by: Stefan Reinauer <stepan@coreboot.org> git-svn-id: svn://svn.coreboot.org/coreboot/trunk@6127 2b7e53f0-3cfb-0310-b3e9-8179ed1497e1
