I don't have access to HPUX unfortunately: I could install it on a
machine I have but I lost my disk burner. Maybe something to do in
winter ;)
I tested on Solaris now (i386-pc-solaris2.11, cfarm215) and it
bootstrapped fine.
I can't get onto the AIX machine on the cfarm, I will open a ticket, but
I'd say it's not a blocker.
