avview keeps Segmentation faulting when I try to start
it up with the km_api_drv and km_drv modules loaded. I
have an ATI All-in-wonder Radeon card. I am getting the
following output in kern.log:

Any help would be appreciated. I am using a MEPIS
distribution which is based on Debian. I am using
XFree86 v 4.3.0.1 If I don't load the km_drv module, I
can see tv coming in fine and it appears to be using
the XV extensions without a problem, however, everytime
I insmod km_drv and start avview I get a Segmentation
Fault right as avview tries to output STATUS to my
/proc/km/control0 file.

    Should be fixed in km 0.6.1
