Thank you for the testing!  Xorg working confirms that uvesafb really
is the source of the problem.  This is good to know.  I have hope that
this issue is fixed by commit 0ad60b2a89d6d387236466e0bcdd61ac489fca37
that loads uvesafb only if it cannot already detect a frame buffer
device.  I do not have a downloadable image for confirming the fix
though.

Sorry I did not think of checking the presence of /dev/fb0 earlier.

Florian
