No problem, it happens :)

I just rebuild 2.6.15-rc5-mm2 with that patch applied and I can
confirm that it fixes the problem.
So, I guess I should add

Acked-by: Jesper Juhl <jesper.juhl@gmail.com>

Andrew, could you please merge that patch from Antonio?



One small detail; With 2.6.15-rc5-mm2 I see a small (rather
insignificant) difference in behaviour compared to 2.6.15-rc5-git1
just at the time when the video mode is switched at boot.
With 2.6.15-rc5-git1 it goes straight from the text mode display to
the graphical one with the boot logo in the top left corner. With
2.6.15-rc5-mm2 + your patch I get a brief, split second, image with
random green/grey/white pixels in the location where the penguin
appears a few ms later - then everything is normal.
No big deal and it doesn't bother me, just thought it might be
something you'd want to know about...
