Comment 43 for bug 559163

Add "nodemodeset" to the end of the boot line in grub (without "")
you can try it first when you're booting.

I added it to the grub.cfg and works flawlessly.
"linux /vmlinuz26 root=/dev/disk/by-uuid/626f55f1-1946-46e4-9b74-47d00bb9e119 ro quiet splash nomodeset"

Hope it works for you all too ;)
