Re: [PATCH] s3_bios and lcall $0xc000,$3

I'm talking about S3 (sorry typo before when I said S4==S5) - if I've
read the specs right (and experience does match this), the i830 video
card looses all state when switched to S3.

Pavel, really, we need to provide a better way to reinitialize
the VGA subsystem.

And you need to make no assumptions about the state - on an i830 (and
others, no doubt), S4 == S5 for the video subsystem.

Are we talking swsusp here? No, subject says S3. So you have typo
there?

Anyway going without assumptions is pretty hard, as it requires
in-kernel support for all the video cards. And that's hard. [Power-on
initialization of cards is different; you have to setup memory timings
etc.]
