No experience with these personally. Don't recall anyone else on the 
list talking about them - most of the mac talk has been about laptops 
and g3 imacs.

The space is there - or at least, was for me, on g3 imac and ibook - if 
you install OS X first. The boot partition has to be in the first 800mb 
of the HD - I got caught out by this first time I tried installing 
Ubuntu on the imac. You do have to format the partition and mark it for 
the bootloader, after which Ubuntu will do the work. As I recall, 
ubuntu tried to create a boot partition at the start of the free space, 
which failed with a weird error message. This might be a bug in the ppc 
installer rather than anything else. The HowTo is at least unclear.
