As I think that b comes reserved, I would play around g eventually.
Starting by an other system is undubtly more easy and without using g you can fix the broken system by paxing a by pax -w, fixing the disklabel, then newfs a, and paxing back by pax -r -pe to a. If you have only that system, more or less (at your own risk only after dbl checked the suggested list): 1. I would pax -w all the content of a to /home/mya.pax; 2. I would umount /usr/X11R6 3. I would copy content of g to /usr/X11R6/; 4. I would free g; 5. I would pax -r -pe content of mya.pax into g; 6. I would edit /etc/fstab: mounting g to /, commenting the mount of a; 7. I would restart the system; 8. I would fix the label of a and free a; 9. I would pax -r -pe content of /home/mya.pax into a; 10. I would edit /etc/fstab: uncommenting the mount of a to /, commenting the mount of g; 11. I would restart the system; 12. I would free g; 13. I would move content of f/X11R6 back to g. Pls dbl check to work on the correct partitions in both the cases.
