"[...]this, they say, cost about $40 too much, and about 20,000 Iowans 
 bought [Windows] 98.  Which gives us a tab of $800,000, i.e. the
 equivalent of a rounding error in Redmond's vast war chest." -The Register

Linus posted a patch for this:
http://marc.theaimsgroup.com/?l=linux-kernel&m=102446529018948&w=2

The following patch that is already in Linus' BK repository fixes it:

You only think this is a free country. Like the US the UK spends a lot of
time explaining its a free country because its a police state.
