I would since the error message you get points to the specific
filename /dev/fb0. But note the "29, 0"  for /dev/fb, which means
for a second one it would be "29, 32". If you feel brave
delete the /dev/fb and create a new /dev/fb0. I wonder what would
happen if you rename /dev/fb to /dev/fb0. Just be cautious and
try whatever you're comfortable with.

Probably most people do the same. Network installs (in particular NFS) are
very efficient.
