Upgrading Solaris 10 U8 to ip_fil5.1.0

Hello again.

I'm trying to build ipf 5.1.0 on Solaris 10 U8 (kernel 142901-11) on 
amd64. Everything builds and installs fine, but when I try to load the 
ipf module I get these errors:

May 19 16:45:38 dmk-test4 genunix: [ID 819705 kern.notice] 
/usr/kernel/drv/amd64/ipf: undefined symbol
May 19 16:45:38 dmk-test4 genunix: [ID 826211 kern.notice]

May 19 16:45:38 dmk-test4 genunix: [ID 472681 kern.notice] WARNING: 
mod_load: cannot load module 'ipf'

I found this old related thread
http://marc.info/?t=119223191000001&r=1&w=2
but the fix in that thread doesn't appear to apply to 5.1.0.

Here is ldd output if it is helpful:
$ ldd /usr/kernel/drv/amd64/ipf
        misc/hook =>     (file not found)
        misc/neti =>     (file not found)
        misc/md5 =>      (file not found)
        drv/ip =>        (file not found)

It appears that the netinfo interface changed at some point. I tried 
changing the function names to the 'new' ones in solaris.c but that 
ended in kernel panic when it booted up. Apparently it is something more 
complicated than that.

Thank you for any assistance.
