There was a thread on acpi-devel about POSTing VGA ROM after resume: http://marc.theaimsgroup.com/?l=acpi4linux&m=109023076427394&w=2 The code does a real mode switch in kernel and execute the ROM. Ok, doing that in userspace is more elegant, but that code is not a mess (though it's arch dependant). Btw, how do we POST non-x86 (eg. ppc) video boards? I don't think that there's x86 code in their ROM... > 7) Mode setting from normal user space - devices will have a standard > IOCTL accepting a mode string like fbdev currently uses. sysfs?
