I am looking into getting a non-Apple CRT screen to hook up to my 12" iBook. Once I install the "mirroring override Hack", while I be able to get high resolutions with the 32meg Video card? And will it really slow things down as it is used to maxing out at 1024x768? Also, does this hack end my warranty on the iBook? Even though it's sofware and not hardware being added? Thanks in advance.
