[Bug 861048] Re: have really quick '_' on boot before first purple screen

[Colin Watson]

I've added code to disable the cursor as early as sensibly possible in
GRUB, and I still see a brief blinking cursor on my system.  However,
it's possible this will help on other systems, so I'll upload it anyway.

The remaining possibilities are:
 * the cursor is blinking while GRUB is uncompressing itself (it *might* be possible to add very early assembly code to disable the cursor, but to be honest I'm not sure I'm prepared to do this)
 * the cursor is blinking while the BIOS is loading GRUB, which we can do nothing about
