Please unblock package xserver-xorg-video-geode
This is a small documentation fix.
It patches the upstream README to add information about what cdmline option is needed to be able to use this legacy X driver on a Linux kernel newer than 3.xx without having to disable vesafb. This has been a long-standing issue and was finally resolved via info provided by the Debian kernel maintainers. The bug was reassigned to this package and fix as shown in the debdiff.
The package still builds with what's in Unstable and runs as before on Testing.
debdiff attached.
Thanks!

+ 03_Mention-iomem-relaxed.patch
+
+ Fixes a long-standing issue that prevents this legacy X driver from booting
+ with stock Linux kernels version 4 or newer. Merely adding a cmdline option
+ makes vesafb and legacy X drivers like this one coexist peacefully again.
+
+ This short patch to the upstream README mentions iomem=relaxed as the fix.
+
+ Thanks to Ben Hutchings for figuring this one out.
