This is where (at least on my system the Video ROM and System ROM resides
-- and that's properly allocated in /proc/iomem, so rsrc_mgr.c excludes
it... Might it be that your plx9052 module doesn't check it the same way?

> 000f0000-000fffff : System ROM

See for yourself, these resources aren't available on your system, either...
