AFIK, POST on S3 resume is not mandated by the ACPI specs, so I'll assume we'll have to do it ourselves: 1. The "lcall $0xc000,$3"-kludge in wakeup.S doesn't even know the PCI slot/function number, and it is probably way too early as bridges etc are not awake yet. 2. POST-on-VT change in X11 can be made to work but is rather dirty and it doesn't fix the text consoles. 3. POST using vm86 from radeon_pci_resume is probably The Right Thing (tm): It knows the PCI slot/function and it happens at the right time wrt bridges and stuff. This requires someone with the knowledge to write the lines of code and the energy to make it work. (Having a black screen as the only diagnostics isn't very inspiring in the long run.)
