Thanks, works.
Two seconds delay looks excessive, but it seems really be needed, trying

How about sending out messages on status changes (i.e. edge not level

CONFIG_VGA_COREBOOT=y in seabios.
That'll give you a vgabios which does vga text mode emulation on top of
a coreboot framebuffer.

Yes (or manually add the rom via cbfstool).
But CONFIG_VGA_ROM_RUN must be "n".

Hi,

Agreeing here. We have PAE. Non-ancient 32bit kernels should support
and use it, for both security reasons (nox support requires PAE page
table format) and accessing physical address space above 4G.

Not sure how coreboot+seabios is configured by default.
I see that too when running with coreboot native graphics.

That alone is reason enough to prefer c99 over c89 IMHO.
