As Jeff wrote , PAL is a TV encoding. This means that hacking the 
Geforce bios wont help much , unless you hack the right things , like 
the part which defines which standard it uses in the tv output....
BUT , you dont need to hack it..  I dont know about linux (because I 
never tried to use a TV with my computer in linux , just in windows), 
but on windows you can configure the card to use the PAL standard on the 
TV-out. Take a look at the readme for the Geforce drivers and there may 
be a option to use PAL on linux. If you dont find any , go to windows 
and configure the card to use PAL and see if this config works after 
rebooting back on linux....
