framebuffer + suspend/resume

framebuffer works fine on my laptop, but after any form of suspend and resume the screen gets garbled. X works fine though, it's just the screen in console that gets messed up. Is there anyway to "reset" the console screens somehow after a resume?

caveats section says:

Note that I am using a bootsplash framebuffer console. If you have problems with the screen garbled after resume, try vga=normal as parameter. Alhough Documentation/power/video.txt says that framebuffer consoles are likely to screw things up, it does seem to work for me (tm) using vesafb. Powermanagement support in framebuffer drivers is still a little flaky, so you might be lucky - or not. ;-) Documentation/power/video.txt from the linux kernel source has some clues, you should read that if you have problems with your video.

Thanks again, phrakture

So, I guess there's nothing to do about at this stage. I just wanted some nice eye candy when suspending, but it's not the whole world...
