Before doing anything else, you'd consider moving forward to current

Then talk your customer (isn't that actually your vendor?) into putting
work into a newer kernel. Maybe you can diff you their changes agains a
2.4.2 from either linux-mips.org or 2.4.2 from Linus and try to
forward-port the changes to current 2.4.x or 2.6.x ...
