iMac dual monitor hack

[Mike Fuller]

Thanks to Neil for alerting me to the fact that G5 iMacs (and G4 ones 
too and some iBooks) can support dual monitors rather than just video 
mirroring. It appears to be one of the items that Apple "turn off" in 
some machines, I guess so that the more expensive ones appear more 
attractive to buyers. Now I just need a cheap LCD monitor to try it out 
with my G5 iMac.

For those interested here is a link for the discussion and hack to 
enable it:
