grub(-legacy) 0.97-46, text-mode only. I refreshed the MBR for testing, no 
changes. That the wallpaper makes a difference is a bit strange, but might 
hint at a problem with setting the framebuffer (I'm not sure, but the 
probability for the boot to succeed seems to be higher with vga=0 for me).

For testing, I've now switched to grub2 (no graphics, simple grub.cfg), no 
changes, the most common error message is
	Decompressing Linux... Parsing ELF... done.
	Booting the kernel

The other traces which appear sometimes are just too badly cut at the top.

What is strange though, is that there are no definitive results, while I 
wasn't able to boot 2.6.26-1-686 with virtualbox-ose 1.6.4 so far, it just
now succeeded once, while a preemptive kernel continues to fail booting (at
least with a much higher probability, even that one boots rarely).
