[g-i] Graphical installer and PPC systems

[Attilio Fiandrotti <fiandro@tiscali.it>]

Hi

Reading reports about the PPC version of the g-i, it came to my mind an 
old, yet unsolved, bug [1] that caused crashes on PPC boxes with some 
particular grapic cards installed.
No one ever investigated deeply enough to state if that was related to 
DFB 0.9.22 or to the DFB backend contained in GTKDFB 2.0.9 as, AFAIK, no 
one ever tried to run a recent DFB backend togheter with DFB >=0.9.24 on 
a PPC box.
As some PPC users may experience annoying crashes, i suggest to disable 
DFB's hardware acceleration by default, at least until we switch to a 
newer stack of GTKDFB+Cairo+DFB libraries.

friendly

Attilio
