i have a new IBM X61 tablet. i'm about to attempt a Vista-OSX dual boot using kalyway 10.5.2.

it has vista pre-installed AND the IBM recovery partition (no optical drive)
i want to chop the vista partition in half, put OSX on the new partition, and preserve the recovery partition if possible (so i can use it for the vista partition if needed in the future).

what's the easiest way to do this? can i just use GPARTED to resize the vista partition and create a new one in the unpartitioned space?

i did this once before on a Dell PC - i resized an XP partition with GPARTED, put vista on the new partition, and it just worked. bundled vista bootloader was there and worked.

i've done a lot of reading and lot of searching but frankly i'm confused.
