Thought I'd share with you a little gem:)
Using the standard Solaris 10 64bit template in Vmware Fusion (I assume it'll work for Windows as well, but not tested) and the JaS 10.5.2 iso, Leopard installs straight, no tweaks required
Install is very FAST and uses the SCSI controller for the disk, rather than the slow virtual IDE drive.
The VM is extremely useable, everything works except sound out of the box (which I would expect is sorted in other threads on the forum). USB all fine.
Leopard is nearer Solaris than FreeBSD anyway
Cheers
scooby.
