Yes. I have tried a lot of mount_XX variants.

I guess it fails because it's a set of two floppies that load
the kernel into ram so the super block might not be where mount
wants it to be.

disklabel vnd0 shows :

a 2880 4.2BSD
d 2880 unused

So I tried mount /dev/vnd0a /mnt

(biiiip! incorrect super block)

I have tried of lot of -t variants but it doesnt seem
to work.

Im going to burn on a RW the image of g4u CD, then dump
it to a file, vnconfig it, replace its 3.1 G4U kernel with
a 4.0_RC5 one and burn it again.

(the 4.0_RC5 has support for the machine's ethernt while 3.1
does not)
