Note that this is only true for the FRI2 using the fastboot UEFI
firmware. Most users will have this version, but the Kontron supplied
firmware is PC BIOS and does indeed support VESA. That said, neither is
particularly fast so one that works on both is preferably.

Is there nothing that can be done about the 800x600 resolution?

I would note the bit about the firmware versions in the commit log. This
is relevant as the README does document the usage of both types of
firmware. Speaking of the README, I believe the VESA driver is mentioned
in there and should also be updated with this patch.
