Modified Files: src/sys/arch/x86/x86: genfb_machdep.c Log Message: x86/genfb: Re-enable shadowfb by defualt for now. Something makes radeondrmkmsfb, at at least, extremely slow, and it's not yet clear what, and shadowfb=true fixes it. I verified that the framebuffer pages are correctly getting mapped write-combining, so the page table entries aren't the problem -- not sure what is the problem.
