I honestly have a hard time believing that GRUB wouldn't work on the pSeries
550 when Yaboot works. I have a pSeries 750 at home and will at some point
try to install Debian on it, too.
I would suggest updating the firmware in your case. If that still doesn't help,
it should be reported as a bug against GRUB upstream.
