I do not use linux-headers-2.6.x on my Qube2, but iptables still b0rked on anything higher then 1.2.11-r3. If I am correct then mips-headers is the equivelant of linux-headers? In that case I have 2.4.21-r3.

My Qube2 acts as my firewall and so I have tried several versions the first time I installed it.
At that time iptables wasn't marked stable on mips.

I just don't understand why iptables needs that file at all, I can't find anything in it that uses it. I'm going to search again, and I will post my results once I figure it out.

iptables doesn't need it. It's one of those funky #include chains. include A includes B which includes C which includes Q and so on until it tries including a file it can't find. This is because there are a series of mach-* machine subdirs in include/asm-mips that each contain headers specific to a particular machine type (like spaces.h, among other things). I haven't delved into the specifics (someone else here can explain it more), but when the kernel builds, based upon the configuration of the kernel, it knows which include/asm-mips/mach-* directory to look in to snag the headers it needs. Userland doesn't know this, so for headers used in userland, you need to patch things abit. Otherwise, they break. <-- appCompat patch used in Gentoo's linux-headers 2.6.10 ebuild. It lacks mips-specific bits, but you can look at how x86 handles some of its include/asm-i386/mach-* sections for how we're working around these issues. It's all a hack really, until someone either fixes userland to never use kernel headers, or the kernel-side finds a way to create userland-friendly headers (but I don't see any of this happening anytime soon).
