i can only repeat what steve said here - i'm one of the people
running XFS on the ppc (but due to time constaints not very up
to date at the moment) ... so it's not sgi who is to blame here
- but also i mentioned that there's a problem with acl's in
my ppc readme which was at least some time ago referenced in
the FAQ (i'm offline right now - so i can't check) ... please
read on ...

i tried to get this working some time ago (changing all the syscall
stuff in the files above) but ended up with some deeper problems
which i tried to debug but did not find a solution for in the limited
time i had ... but it's some time ago now again - maybe worth trying
it again ...
hope that helps - and maybe good luck :-)
