Comment 8 for bug 745304

I finally tracked down that the issue is fixed by upgrading grub-common and grub-pc from 1.99~rc1-6ubuntu1 to 1.99~rc1-8ubuntu1. What seems to be fixing it is some changes to check for hardware support before using gfxpayload=keep. I verified that with the old grub I got gfxpayload=keep, and with the new grub I get gfxpayload=text.
