There are actually two others (MIPS2 in particular) hidden on the vendor 
branch (ATHEROS) but orphaned from HEAD (don't get me started about 
sourceforge and how impossible it is get CVS repo help).

I'll see what I can do about the ident string.  The version string shows up 
many places elsewhere.

As to differences, the Linux versions are compiled separately but they have 
identical ABI's (at least they worked in my testing).  I'm not sure if there 
are actual differences or why the two binaries aren't identical bit for bit.

If netbsd has 0.9.6.11 then that's the latest. FreeBSD is lagging (!).

They are supposed to be OS independent.  All the OS-specific glop is in the 
ah_osdep.c file that is supplied in source form.  The naming convention 
reflects the gcc tag used to build the hal.o binary.  If you can't just grab 
a hal.o from sourceforge and use it I want to know and will fix that.
