Hi Jani,

thx for looking into this by the way. This looks a little strage to me, because
I observe a higher resolution in the boot menu for uefi compared to csm.
Anyways this is a firmwae bug, right? Dell sells these machiens with some kind
of linux support, so they might even be willing to fix this. :)
