RE: Change endianess on G4?

I went and looked up the Microsoft KB on the issue:
http://support.microsoft.com/kb/827904

<snip>

Virtual PC for Mac Version 6.1 and earlier use a feature that is present
in the PowerPC G3 and the PowerPC G4 named "pseudo little-endian mode".
Virtual PC for Mac uses pseudo little-endian mode for increased
performance when it emulates a Pentium processor. Virtual PC for Mac 6.1
must use pseudo little-endian mode to function.

The new Power Mac G5 processor does not support pseudo little-endian
mode. Therefore, the current versions of the Virtual PC for Mac program
do not run on the Power Mac G5.

The lack of switching endian mode was the reason Virtual PC could not
run on the G5/PPC990s.

As it would use this feature to speed up emulation of an x86 CPU, kinda
neat all in all.
