The code for loading the uvesafb module looks like this:
(invoke #+(file-append kmod "/bin/modprobe")
"uvesafb"
(string-append "v86d=" #$v86d "/sbin/v86d")
"mode_option=1024x768"))))
So it should call
modprobe uvesafb v86d=/gnu/store/…-v86d-…/sbin/v86d mode_option=1024x768
and it should be impossible for v86d to be missing. On x86_64 and
i686 at least, and on other architectures uvesafb will not be loaded.
Then again, if the GUI works because of other drivers already, we need
not fix it, I think. Also I still believe the error comes because
other drivers already reserve needed memory -- passing nomodeset
should make sure they don’t. Except if vesafb or xf86-video-vesa is
loaded, which is not the case in the installer.

Florian
