I haven't tried S3/S4 yet, but I suppose the problem will be similar on my ATI
Radeon 9600 M10 NP laptop. Simple question: in which way X restores the screen?
I mean, I've seen other posts on other mailing-lists about POST command which
can be restore LCD after resume, but I don't know how I can do it.. Could
explain me or provide some docs?

Another simple question: is there a documentation about 'radeonfb'? If I compile
it in the kernel, I've no problem, but as modules I get this error:
	radeonfb: Unknown symbol fb_find_mode
