No, really, the Agnus in the NTSC and PAL machines is that same.  The clock 
crystal is _slightly_ different (28.14 vs ~28.09Mhz) but this is not necessary
for PAL generation on a multisync monitor since it can sync to a slightly off
PAL signal and a PAL monitor (TV w/RFgen) couldn't.  The only other difference
is a jumper (for which I saw a switch hack on FidoNet) which determines default
mode for the machine.  The only problem I have seen (other than using it with
the flicker fixer which is timed for NTSC) is with losing some of the bottom
lines in lieu of the background color (the pointer also disappears there).  I
am not certain, but I think if you run morerows and give the workbench more
lines to begin with, that might fix the lost lines (then again the jumper could
hardware generate a 60 vice 50 Hz vert sync - I have the FF so I probably won't
investigate further).
