Damnit. numpages & .37

[richard@iguana.co.nz]

Ok, here's the problem, and its a multi-fold one, as usual, and its not
particularly netfilters fault either, I just figured someone here might
have an idea on solution.

My routers run off floppy disks, with 2.3* kernels and netfilter enabled.

The damn kernel guys broke initrd on 2.3.38+, with no fix in sight as yet
(.41 still broken)

Ok, no problem says I, I'll just backtrack down to .37 and use that
instead until they fix...but..netfilter .15+ requires the symbol
num_physpages, which .37 and below don't export.

So, what is the best solution here? any way I can make .37 export that
symbol properly without breaking initrd? or vis-versa, any way of
replacing the requirement in netfilter .17 so that it doesn't need
num_physpages? hard code some safe value? or another name?

Richard.
