Anyone have any success with this family of hp laptops? Any pointers towards kexts or installation options would be helpful. I get all the way thru the installation but hang at the loading screen post-install.. verbose says its "waiting for root"

(Ive tried Kalyway 10.5.2 and now Leo4all .. both hang at same screen)

specs:
AMD Turion 64 x2 processor
2GB DDR memory
256MB NVIDIA GeForce Go 7200
160GB 5400RPM SATA Hard Drive
LightScribe 8X DVD+/-RW with Double Layer Support
Altec Lansing speakers built in
3 USB ports, USB 2.0, ExpressCard/54 Slot, Video Out, Integrated Consumer IR, 1 RJ-11, 1 RJ-45

Thanks in advance..
