I observed the same behavior on my AmigaOne, if the PAGE_COHERENT flag was
set for page mappings by CPU_FTR_NEED_COHERENT. The 7448 CPU doesn't need
CPU_FTR_NEED_COHERENT to be set (no CPU bug that needs to be worked
around), but there is no define for the 7448 in arch/powerpc/cputable.h in
kernel v2.6.20 (but it's in v2.6.22!). Thus I guess it is detected as a
744[0|5|7], which have this flag set.
On the other side my hardware is _very_ buggy, so it's unlikely that this
could be the problem on your hardware.
