Ole Rohne has patch to do just that at http://dev.gentoo.org/~marineam/patch-radeonfb-2.6.11-rc2-mm2. + (8) on some systems, you can use the video_post utility mentioned here: + http://bugzilla.kernel.org/show_bug.cgi?id=3670. Do echo 3 > /sys/power/state + && /usr/sbin/video_post - which will initialize the display in console mode. + If you are in X, you can switch to a virtual terminal and back to X using + CTRL+ALT+F1 - CTRL+ALT+F7 to get the display working in graphical mode again. + Now, if you pass acpi_sleep=something, and it does not work with your bios, you'll get a hard crash during resume. Be careful. Also it is safest to do your experiments with plain old VGA console.
