This is due to r300, adding the following option in you card device
section should fix what you see :
Option      "XaaNoScanlineImageWriteRect"
Option      "XaaNoScanlineCPUToScreenColorExpandFill"

Maybe some check on ppc could be added ? There is still no
fix or know way to ask for endianness conversion on r300 ?

Do you use the r300 dri driver ?
