grub2 traps

Recently, I upgraded to grub2. I did expect problems, and yes I got them. Fortunately, machine did boot after grub2 install, and initially everything seemed to work, and after switching grub2 to (very slow) 1024x768 mode, I got my vesafb to work, too.

But then I noticed warning about vga= option being deprecated in favor of gfxpayload option (is it gfxpayload=, or set gfxpayload=?), and switched. Unfortunately, without doing test boot... and then I forgot, and then I wondered why my vesafb does not work.

Ok, so it seems that you need both gfxpayload= and vga= options...
