KPearPC is PearPC 0.4pre_cvs with AltiVec support, precompiled for Linux, plus a little graphical interface. Note that kmdr-executor must be installed in a recent version.
You can download it from http://klik.atekon.de/cmg/kpearpc.cmg
On klik-enabled systems (e.g., Kanotix) you can directly run it from this link, on all other systems you must unpack the cmg file, e.g. to /opt
/usr/sbin/cramfsck -vx /opt/kpearpc ~/kpearpc.cmg
You can then run it using /opt/kpearpc/wrapper
KPearPC is released under the GPL. Please send me your improvements/contributions.
