Of course the machines that need uvesafb to show the installer also
later have problems showing Xorg.  Maybe until Xorg on installed
systems without Kernel Mode Setting works fine without manually
fiddling with uvesafb or nonfree drivers, there is no use making the
installer work.

Perhaps uvesafb could somehow be made to work automatically, however
on one of my computers uvesafb can only be used after =E2=80=9Echmmod o+r=
w
/dev/fb0=E2=80=9C which is a security issue, I suppose.

In fact nomodeset was needed on a friend=E2=80=99s AMD GPU system.  Proba=
bly
one could blacklist yet another AMD graphics module instead of passing
nomodeset.  But then the installer on AMD systems where the module is
working fine would be limited to uvesafb.
