Nope, it works fine here w/the FC2 2.6.8-1.521 kernel. RH disallowed the use 
of sys_* calls entirely, which isn't being done (yet) in the kernel.org 
sources, so there's an additional change you need to make in ivtv-firmware.c.

Yup. I posted a patch to the ivtv mailing list just yesterday. Essentially, 
all you need to do is take the load_fw_direct function from a newer version 
and substitute it for the one in 100z.

Both 108k and 108m kernel panic my EPIA/PVR-350 system and 112t segfaults. The 
patched 100z loads without a problem.
