Darren,
I am replacing Sun's 4.0.2 with 4.1.8 on a Solaris 10 x86 box, and I am seeing some of the issues that others have noted, in regards to my how-to writeup on this.
On my Sparc box that I had no problems on, I found that ipf, ipfs, ipnat, and ipfstat were installed in /usr/sbin, with symlinks in /sbin pointing to them. On x86, the install script put the files in /sbin, with nothing in /usr/sbin.
The path for Sun's /lib/svc/method/ipfilter on lists /usr/sbin, so the load for ipfilter and ipnat fails on the x86 box. Please fix.
