Details:

I have a problem when booting on GRUB while using GRUB_GFXMODE=auto on BZR
Revision 4820. I have a Inspiron 14z, with hybrid graphics (ATI / Intel,
Muxless system), bios revision A10, booting with UEFI. 

If I set the mode to auto, it just hangs up and a small screen corruption is
seen on the screen. If i put GRUB_GFXMODE=text on /etc/default/grub and then
regenerate the /boot/grub/grub.cfg, the system works correctly.

More specs:

OS: Arch Linux x86_64
GRUB: grub-efi-x86_64-bzr [Rev. 4820]
Linux Kernel: 3.8.6-1-ARCH

Output of lspci and dmesg | efi on files.
