Shrinking Windows Vista for openSUSE 12.3

is the ultimate goal so I started with cleaning up the HDD, defragging and shrinking the C: drive.
openSUSE 12.3 and KDE 4.10

The shrink did not give me the free space I was hoping for.

This is after the shrink:
167Gb Capacity
133Gb Free
58.44Gb unallocated. <---this will hold openSUSE and I was hoping for more. Is it large enough ?

I had read where Vista keeps some sizeable system files near the physical end of the drive hence restricting how much space I could recover.
I used the Windows shrink program.

Am I pretty much stuck with this or have others figured out a way around it ?

thanks
