Sigh. This means *a lot* of bisecting. Is there any ker

Yes, the messages change correctly. For example, booting with `vga=0x318' only
correctly gives
intelfb: Initial video mode is 1024x768...@60.
However, the screen stays blank.

Alas, it still fails. After compiling the current git kernel with AGP_INTEL=Y
and FB_INTEL=Y, I booted with
vga=0x31a video=intelfb:mode=1280x1024
which spits out the following i

I have no idea :-) Krzysztof Helt has sent a patch to the linux-fbdev-devel
list already. In my case, I have no VESA driver selected at all, so it's no
wonder that I get an empty sc

Yes, plenty of them, like 0x307, 0x31B, or 0x305. None of them work.
However, I've now analyzed the situation more closely, and the change from good
to bad bisect just hides the rea

OK, I did bisecting as follows:
git bisect start v2.6.28 v2.6.27 -- drivers/video
and I found that this is good (this is, no black screen):

I've now downloaded the git archive of the kernel. The above assumption
unfortunately is incorrect; the break for my video card happens between
2.6.27 (which is OK) and 2.6.28 (which
