Since this occurs during installation, I'm not sure how easy this is going to be to test... Possibly switch to a terminal early in the installer, install the deb, and then continue the installation? If someone knows of a better procedure for testing, please share it here.
The description of the patch is, "Screen size changing should leave FB alone when X is inactive." I'm just making a wild guess that perhaps at some point during installation, one of the packages does a screen size change before X has been made active, which then affects the framebuffer which for this hardware results in the screen corruption described in this bug.
Here is a deb including the aforementioned patch, could someone test this?
