Oops, why you think so?
It's a rather hard show stopper that hapens with the plex86 module
across all different hardwares I've tried so far. It seems to be a principle 
problem of the magic for figuring out the physical pages of the
loaded plex86 module.

But maybe I was not specific enough: the error is as follows

    ./misc/../kernel/plex86.o: init_module: Invalid argument
    Hint: insmod errors can be caused by incorrect module parameters, including 
invalid IO or IRQ parameters
    The kernel module failed to load!

And /var/log/messages/shows

    Apr 24 20:59:51 schlepptop kernel: plex86: retrieve_vm_pages: ret with n=0
    Apr 24 20:59:51 schlepptop kernel: retrieve_vm_pages returned error.
    Apr 24 20:59:51 schlepptop kernel: retrieve_monitor_pages returned error

The code failes at the the following line of retrieve_vm_pages 

    /* If page isn't present, assume end of area */
    if ( !pde->fields.P || !pte->fields.P )

This condition is true for the very first page that is checked because
pte->raw equals to 0

No idea why, can anybody enlight me on that??

Ps.: this doesn't help!
