Yes. That's what I'm doing:


* [booting 2.4.5 and starting XFree86]
------
* # ./load_module.h
  The kernel module is sucessfully installed. 
------
* $ ./plex86 -f ../conf/pragma                   [first attempt fails!]
  Processing command-line options
  Opening VM (/dev/plex86)
  Processing config file ../conf/pragma...
  Allocating 16MB of physical memory in VM
  ioctl ALLOCVPHYS: : Cannot allocate memory
  $
            
                                [doesn't work; /var/log/messages says:]
            kernel: 37 monitor pages located
            kernel: host CR0=0x8005003B
            kernel:
            kernel: plex86: vm_t size is 133332
            kernel: retrieve_phy_pages: P==0
            kernel: plex86: allocVmPages failed at 2
------
* $ ./plex86 -f ../conf/pragma 
                                                 [second attempt works]
------
* [exiting XFree86]
------
* [restarting XFree86]

That would be a reasonable explanation.
