Subject: [PATCH] surftab-wintron7.0: new device (TrekStor Surftab wintron 7.0)
 (!290)

This device is x86_64 and has a 32-bit UEFI, so I need to install
32-bit grub (AFAIK it's the only bootloader capable of loading a 64-bit
kernel from 32-bit).

The grub-efi-x86 package has been generated with pmbootstrap.
