I suggest to do it the other way around:
  .if ${LINUX_OSRELEASE} == "2.4.2"
  IGNORE
  .endif

This way the current default is to ignore and anyone who plays around  
can do so. It also allows us to use any 2.6.x number we want (in case  
we think another one is more appropriate) without the need to change  
the port. WE just want to protect the innocent, everyone else is  
allowed to shot into their own foot.

Bye,
Alexander.
