The higher-end ones would certainly NOT be supported on anything other
than AIX.  However, provided you don't require OFW support for your
framebuffer (ie: willing to use SMS through a serial port), you can
probably toss in any ol' PCI graphics adapter and Linux will DTRT.

POWER3 (and to some degree POWER2-SC) and later are perfect supersets of
PowerPC, and, therefore, will run Linux quite happily.  In fact, the
POWER4 and POWER3-II systems at work all changed their banners to
"PowerPC" with the last round of firmware updates I did because IBM wants
to hammer that point home.

The only thing I -really- hate about my 43P-150 (not 44P) is the case
design, which is the third-worst I've ever seen (the two worst being
the Sun Ultra5/10 platform).  The system isn't terribly fast, but it's
plenty usable for a desktop.  In fact, with a GXT800P, it's
significantly snappier than this AXi, and nearly as much so as an
Octane with MXI graphics.

The only reason it isn't on my desk is because I can't get two decent
graphics heads on it due to the craptacular case design.  A pair of
GXT800s would -rock-.
