Hi,

This isn't in the official grub sources yet, but it is very useful and as far as
my system goes, it works like a treat. 

This is a patch written by Erich Stefan Boleyn which fixes/works-around some
Gate A20 issues with stage2 of the bootloader. Specifically, this fixs problems
with some BIOSes and USB Keyboards being inoperative in grub. Even though the
BIOS settings indicate that the USB Keyboard support is enabled (aka. legacy
mode), grub still doesn't detect it. This patch fixes this problem. I've tested
it on both grub-0.90 and grub-0.92 in the portage without any problems.

I just packaged it up a little and submitted it here.

Cheers,

Alastair

Alright, I've added the patch to the still masked grub-0.92.ebuild. Please
reopen the bug if that's not satisfactory, and I'll consider another revision of
the 0.90 ebuild. Thanks!

It would be a great idea to insert the patch that Alastair posted in the 
portage tree ! I guess lot's of modern computers have the USB problem...
I've tested the patch based on the CVS version of grub, and it works ok.
