[PATCH] x86: Don't probe for DDC on VBE1.2
VBE1.2 doesn't support function 15h (DDC) resulting in a 'hang' whilst uncompressing kernel with some video cards. Make sure we check VBE version before fiddling around with DDC. http://bugzilla.kernel.org/show_bug.cgi?id=1458 Opened: 2003-10-30 09:12 Last update: 2007-02-13 22:03 Much thanks to Tobias Hain for help in testing and investigating the bug. Tested on; i386, Chips & Technologies 65548 VESA VBE 1.2 CONFIG_VIDEO_SELECT=Y CONFIG_FIRMWARE_EDID=Y Untested on x86_64.
